View "Tiangongkai", although this complex organic compound is not detailed, it has written many books on the transformation of many substances and chemical processes. In ancient alchemy, dyeing, pottery and other processes, there is no lack of exploration of the preparation and reaction of various compounds. This cadmium dissuccinate derivative, if used in ancient chemical situations, may be related to the reaction of specific substances.
In alchemy, warlocks often involve complex chemical changes in order to seek longevity and make "magic pills". A variety of metals, minerals, and organic raw materials react with each other, or form similar complex organometallic compounds. Although its precise structure was not known at that time, it accumulated a lot of practical experience. This cadmium dissuccinate is either a by-product of a specific reaction or an intermediate product for the ancients to try to synthesize new substances.
In the dyeing process, in order to obtain a bright and lasting color, various plants and minerals are often used as raw materials, which are boiled and fermented. The process involves complex chemical reactions. The structure of organic compounds changes frequently, and the pyrrole and pyrrole structures in cadmium dissuccinate are either related to some components in the dyeing raw materials, or generated to enhance the stability and adhesion of the dye.
In summary, although "Tiangong Kaiwu" does not directly face this cadmium dissuccinate, combined with its records of chemical processes, it can be inferred that this compound may have a certain relationship with ancient chemical practices, or it may be used to explore the products of the material transformation process and have reference value for the study of the evolution of ancient chemical technology.

5- (2- (1,3-dihydro-3-oxo-2H-pyran-2-subunit) -1,2-dihydro-3H-pyrrole-3-nitrile) cobalt diketoate, which is an organometallic compound.
In terms of physical properties: it may be solid under normal conditions, because organometallic compounds are mostly solid. In terms of melting point, the interaction between the organic part structure and metal ions will affect it. The substance contains multiple cyclic structures and conjugated systems, with enhanced intermolecular forces and high melting boiling points. In terms of solubility, due to its combination of polar groups (such as carbonyl groups) and non-polar organic cyclic structures, it may have a certain solubility in polar organic solvents (such as ethanol and acetone), but it may have a low solubility in non-polar solvents (such as n-hexane).
In terms of chemical properties: the carbonyl groups in its molecules are electrophilic, vulnerable to nucleophilic attack, nucleophilic addition reactions, such as acidic or basic catalysis with alcohols, or the formation of acetal or semi-acetal structures. Unsaturated double bonds and conjugated systems allow the substance to participate in a variety of addition reactions, such as the Diels-Alder reaction, and cyclic addition with suitable dienes to construct new cyclic structures. In addition, metal cobalt ions can participate in the redox process, change their own oxidation state, and then affect the reactivity of the whole compound, which may have potential applications in the field of catalysis. Because of the nitrile group, hydrolysis can be carried out. Under acidic or basic conditions, the nitrile group is gradually converted into a carboxyl group or an amide group.

To prepare 5- (2- (1,3-dihydro-3-oxo-2H-indole-2-subunit) -1,2-dihydro-3H-indole-3-one) cadmium disulfonate, the method is as follows:
First take an appropriate amount of 1,3-dihydro-3-oxo-2H-indole-2-subunit related raw materials, and add a specific proportion of the reaction solvent to the clean reaction vessel. The solvent should be carefully selected according to the characteristics of the raw materials and reaction conditions, or an organic solvent such as ethanol, acetone, or an inorganic solvent such as water. Stir well to fully dissolve and disperse the raw materials.
Next, slowly add the reactants required for the preparation of 1,2-dihydro-3H-indole-3-one. The addition process must strictly control the rate, and at the same time closely monitor the reaction temperature. This reaction temperature is very critical. Too high or too low may affect the reaction process and product purity. Generally, it should be maintained at a specific temperature range, or at room temperature, or heated to tens of degrees Celsius, depending on the specific reaction mechanism.
After the above reaction proceeds smoothly and reaches a certain degree of reaction, a sulfonating agent is introduced to promote the formation of disulfonic acid structural parts. In this step, factors such as the amount of sulfonating reagent, reaction time, and pH of the reaction environment all have a profound impact on the formation of the product, which needs to be precisely regulated.
Finally, when the reaction system exhibits the expected reaction characteristics, such as the color change of the reaction solution, the detection of specific indicators, etc., stop the reaction. After filtration, washing, drying, etc., the product is separated and purified from the reaction mixture to obtain 5- (2 - (1,3 -dihydro-3-oxo-2H-indole-2-subunit) -1,2 -dihydro-3H-indole-3-one) cadmium disulfonate. The whole synthesis process requires the experimenter to operate cautiously and strictly observe the reaction conditions in order to ensure the quality and yield of the product.

5- (2- (1,3-dihydro-3-oxo-2H-pyran-2-subunit) -1,2-dihydro-3H-pyrrole-3-nitrile) cobalt dithiophenecarboxylate When using, many things should be paid attention to.
This reagent has specific chemical activity, and should be careful not to touch the skin when contacting it, because it may cause irritation to the skin and cause adverse symptoms such as allergies. When using, be sure to wear suitable protective equipment, such as gloves, protective clothing, etc. If accidentally touched, rinse with plenty of water immediately, and seek medical assistance as appropriate.
Furthermore, the reagent may irritate the respiratory tract, and the use process should ensure good ventilation to avoid inhaling its volatiles. If you inadvertently inhale during operation, causing cough, breathing difficulties and other conditions, you should quickly move to a fresh air place and seek medical attention in time.
At the same time, 5- (2- (1,3-dihydro-3-oxo-2H-pyran-2-subunit) -1,2-dihydro-3H-pyrrole-3-nitrile) cobalt dithiophenecarboxylate or damage to the eyes, wear protective equipment such as goggles during operation. If the eyes come into contact accidentally, rinse immediately with plenty of water. The rinsing time should be long, and then seek medical attention as soon as possible.
Storage of this reagent is also particular. It should be stored in a dry, cool and ventilated place, away from fire and heat sources, and separately from other chemicals to prevent reactions. When taking it, strictly follow the prescribed dosage, do not increase or decrease at will, and the operation process must be rigorous to avoid spills. If there are any spills, deal with them in a timely manner according to regulations.

"5% 2C5- (2- (1,3-dihydro-3-oxo-2H-pyrrole-2-subunit) -1,2-dihydro-3H-pyrrole-3-nitrile) cadmium succinate" is a chemical product. However, its market price range is difficult to determine.
Because the market price is often affected by many factors. First, the availability of raw materials is difficult and the price fluctuates. If the raw material is scarce and difficult to find, or its price fluctuates due to the weather and origin, the price of the finished product will also change. Second, the preparation process is complicated and simple. If the preparation requires delicate methods, strict conditions, labor and time, the price will be high; if the process is simple, the cost will drop, and the price will be different. Third, the state of market supply and demand. If there are many people who want it, and there are few people who supply it, the price will increase; if there is an oversupply, the price will be depressed.
And the wide and narrow use of this chemical also affects the price. For ordinary industries, and for high-end scientific research, medicine and other special fields, its value and price are different. Therefore, in order to determine its market price range, it is necessary to carefully examine the raw materials, processes, supply and demand, and uses in order to obtain a more accurate number. Today, according to what you said, it is difficult to determine its price range.
