In order to know the safety of 2-hydroxyethanesulfonic acid-4,4 '- [pentane-1,5-diyl bis (oxy) ] benzamidine (2:1), it is necessary to investigate from multiple angles.
The chemical structure of this substance is unique, in which 2-hydroxyethanesulfonic acid has specific chemical activity, while 4,4' - [pentane-1,5-diyl bis (oxy) ] benzamidine also has its characteristics. The combination of the two in a 2:1 ratio, or the derivation of different chemical properties and reactivity, has a profound impact on its safety.
In terms of toxicity, if ingested orally, it is necessary to investigate the metabolic pathway in the organism to see if it will decompose and release toxic components, or react adversely with substances in the body, causing organ damage, physiological disorders, etc. If it comes into contact with the skin, check whether it will penetrate the skin barrier, causing allergies, irritation and other symptoms.
If this product is used in industrial processes, production environments, its volatilization, leakage and other conditions or exposure to operators, it is necessary to consider potential hazards to the respiratory system, nervous system, etc. And if the waste from the production process is not handled properly, it will flow into the environment, or have adverse effects on soil, water sources, biological communities and other ecosystems.
However, due to the lack of knowledge of its specific application scenarios, it is difficult to make accurate conclusions. In the field of medicine, its safety assessment must be more rigorous, and it needs to undergo a large number of clinical trials to confirm that it is harmless to the human body before it can be applied. For industrial additives and other uses, it is also necessary to strictly consider the long-term impact on the environment and human health. Therefore, based on existing information, it is difficult to determine its safety, and more professional research and data support are needed.

To prepare 2-hydroxyethanesulfonic acid-4,4 '- [pentane-1,5-diyl bis (oxy) ] benzamidine (2:1), the preparation method is as follows:
First prepare various materials, weigh an appropriate amount of 2-hydroxyethanesulfonic acid, 4,4' - [pentane-1,5-diyl bis (oxy) ] benzonitrile, etc. In the clean reactor, remove the air with nitrogen to create an inert atmosphere to prevent impurity interference.
First pour 4,4 '- [pentane-1,5-diylbis (oxy) ] benzonitrile into the kettle, inject an appropriate amount of organic solvent, such as dichloromethane, N, N-dimethylformamide, stir to dissolve, so that uniform dispersion. Warm to a specific temperature, about 50-80 degrees Celsius, temperature control is stable.
Slowly add an amination reagent, such as liquid ammonia or ammonia gas, and ammonia reaction at this temperature. During the reaction, close observation can be used by thin-layer chromatography or liquid chromatography to observe raw material consumption and product formation. After the amination is completed, 4,4 '- [pentane-1,5-diyl bis (oxy) ] dibenzamidine intermediate is obtained.
Prepare a separate container, dissolve 2-hydroxy ethanesulfonic acid in water or alcohol solvent, stir to promote the solution. Slow the solution into the reactor containing 4,4' - [pentane-1,5-diyl bis (oxy) ] dibenzamidine intermediate. Adjust the pH to a suitable range, about 6-8, and then control the temperature for the reaction at 30-60 degrees Celsius.
At the end of the reaction, the temperature of the system can be lowered, and the solid product can be resolved. Separate the product by filtration or centrifugation. Rinse with an appropriate amount of cold solvent to remove impurities. The product was vacuum dried to obtain 2-hydroxy ethanesulfonic acid-4,4 '- [pentane-1,5-diyl bis (oxy) ] benzamidine (2:1). The whole process needs to follow the operating procedures, control the reaction conditions, and ensure the purity and yield of the product.

The Quality Standard of 2-Hydroxyethanesulfonic Acid-4,4 '- [pentane-1,5-diyl bis (oxy) ] benzamidine (2:1) is related to the purity, impurity limit, physical and chemical properties and many other key elements of this material.
Looking at its purity, when it is required to a very high standard, it needs to be pure and flawless, and the impurity content should be minimal, which should not hinder its performance and application. In terms of impurity limits, all kinds of impurities should be strictly limited, such as organic impurities, inorganic impurities, etc., which need to be determined according to accurate analytical methods and must not exceed the specified values.
Physical and chemical properties are also an important component of Quality Standards. The melting point and boiling point need to be stable within a specific range, which is related to their physical state and stability under different conditions. Solubility should not be ignored, and it should be able to show good solubility in specific solvents to meet the needs of practical applications.
In addition, the pH is also clearly defined, and it needs to be maintained in an appropriate range to avoid affecting its chemical properties and stability due to peracid or peralkali. The moisture content should also be strictly controlled. Excessive moisture may cause its deterioration and performance to decline.
Furthermore, the identification method of the relevant substance is also within the scope of Quality Standards. There needs to be an accurate and exclusive identification method to determine the authenticity of the substance with certainty and not to be confused.
All these Quality Standards are to ensure that 2-hydroxyethanesulfonic acid-4,4 '- [pentane-1,5-diyl bis (oxy) ] benzamidine (2:1) has stable and reliable quality, suitable for various related fields of application.

I look at the "2 - Hydroxyethanesulfonic Acid - 4,4 '- [Pentane - 1,5 - Diylbis (Oxy) ] Dibenzenecarboximidamide (2:1) " you are inquiring about, which is a rather complex chemical substance. It is difficult to specify its price range in the market. Due to the interplay of many factors, its price fluctuates indeterminately.
First, the purity of this product has a great impact on the price. If the purity is extremely high, it is almost flawless, and it is suitable for high-end scientific research or special industrial processes, its price will be high. And those with less purity are used for general industrial purposes, and the price is slightly lower.
Second, the market supply and demand trend also affects its price. If the demand is strong and the supply is limited, just like the principle that rare things are expensive, the price will rise. On the contrary, if the supply exceeds the demand, the merchant may reduce the price in order to sell their goods.
Third, the cost of production is also the key. The price of raw materials, the difficulty of preparation, and the simplicity of the process are all related to cost. If the scarcity price of raw materials is high, the preparation process is complicated, and a lot of manpower and material resources are required, the cost will be high, which will lead to a high price.
I have searched ancient books such as "Tiangong Kaiwu" in the past, but there is no price record directly related to this thing. In today's market, the price of such chemicals may vary greatly depending on different manufacturers and specifications. Roughly speaking, the price per gram may range from a few dollars to tens of dollars, or even higher. This is only a rough guess, not an exact figure.
