What are the physical properties of 2- (4-aminobutyl) guanidine sulfate?
Sodium 2 - (4 -hydroxyacetylaniline) sulfonate is an organic compound with the following physical properties:
Looking at its appearance, it often appears as a white to off-white crystalline powder at room temperature. This form is easy to store and transport, and in many chemical reaction systems, it can be more evenly dispersed, which is conducive to the full progress of the reaction.
Smell its odor, usually almost no obvious odor. This property makes it suitable for some applications with strict odor requirements, such as the use of food and drug-related excipients, without introducing undesirable odor interference.
Measure its solubility, soluble in water, this is due to the presence of sulfonate ions in its molecular structure. This ion has good hydrophilicity and can form a stable interaction with water molecules. After dissolving in water, it can form a uniform transparent solution, which is conducive to the application of chemical reactions in aqueous solutions, pharmaceutical preparations and other processes. In common organic solvents such as ethanol and ether, its solubility is relatively poor, which determines its application range in different solvent systems.
When it comes to melting point, it is about 300 ° C. The higher melting point indicates that the intermolecular force is strong and the structure is relatively stable. During the heating process, a higher temperature is required to destroy its lattice structure and undergo phase transition. This property allows it to maintain its own structural stability during processing or reaction in some high temperature environments, and does not easily decompose or melt, affecting product properties.
Looking at its density, the relative density is about 1.5 - 1.7 g/cm ³, which allows it to be separated and precipitated according to density differences when mixed with other substances, providing convenience for its purification and separation in industrial production.
What are the precautions in the synthesis of 2- (4-aminobutyl) guanidine sulfate?
In the process of synthesis of 2 - (4 -aminopyridine) borate, several things should be paid attention to.
First, the quality of the raw materials is related to the success or failure of the reaction. Both 4-aminopyridine and borate esters need to be purified, and impurities or side reactions need to be produced, reducing the rate and purity of the product. If the commercially available raw materials are impure, they should be purified in advance, and high-purity raw materials should be obtained by sublimation and recrystallization as the basis for the reaction.
Second, the reaction conditions are essential. The temperature control is accurate, and the temperature needs to be adjusted at different stages. At the beginning, moderate temperature rise promotes the activation and contact of the raw materials. However, if it is too high, it will cause side reactions, such as borate hydrolysis and 4-aminopyridine polymerization. Generally, the temperature is controlled in a specific range and fine-tuned according to the reaction process. In addition, the choice of solvent is also critical. It is appropriate to use those that dissolve the raw materials and products well and have no side reactions with the reaction system, such as common organic solvents, depending on the reaction mechanism and requirements.
Catalytic agent also affects the reaction. Or add a specific catalyst to increase the reaction rate and reduce the reaction energy barrier. When used, the amount needs to be accurate, too little catalysis is insufficient, too much will increase the cost, or lead to impurities. And the activity and selectivity of the catalyst must be considered, and the suitable one should be found to make the reaction efficient and specific.
The monitoring of the reaction process should not be ignored. Thin-layer chromatography (TLC) and high-performance liquid chromatography (HPLC) methods are commonly used to know the situation of raw material consumption and product generation. According to the monitoring results, adjust the reaction parameters, such as adding raw materials and controlling the time, to ensure that the reaction reaches the expected.
After the treatment, it is related to the acquisition of the product. After the reaction is completed, the impurities are removed by extraction, washing, drying, column chromatography, etc. During extraction, the appropriate extractant is selected to separate the product efficiently. When drying, the product is avoided from decomposing or absorbing water. Column chromatography selects suitable fillers and eluents for precise separation.
All these things should be carefully treated in the synthesis of 2- (4-aminopyridine) borate to achieve optimum results.
What is the market price range for 2- (4-aminobutyl) guanidine sulfate?
The market price range of (2- (4-aminophenyl) pyridinium sulfate often varies due to many factors such as quality, supply and demand, and source.
Looking at the products in the market, those with high quality, refined and purified products have a high price. Because at the time of preparation, the materials used are excellent, the process is complicated, and the manpower, material and financial resources are expended, so its value can reach tens of gold per gram.
If it is an ordinary commercial product that meets the needs of general industry, its quality is slightly inferior to the former, but it can also be applied to many scenarios. Such goods, due to the slightly lower production cost and relatively sufficient supply, have prices ranging from a few gold per gram to more than ten gold.
There are also crude products with initial production, which are not of high purity and are only suitable for uses that do not require high purity. Such products are easy to prepare and low cost, and the price per gram is only a few gold, or even lower.
In summary, the market price of 2- (4-aminophenyl) pyridinium sulfate is as low as a few gold per gram, and the high can reach tens of gold, depending on the details of the actual goods.)
