Attack again | nuoheng analysis to deeply interpret hydrazine hydrate and hydrazine compounds in drugs

Hydrazine hydrate and hydrazine compounds are often used as reducing agents or nitrogen source intermediates in the process of drug synthesis. These substances may remain in the end products and become impurities, which will strongly stimulate human organs such as eyes and upper respiratory tract, damage liver, kidney and myocardium, and lead to cancer and genetic damage due to their carcinogenicity and teratogenicity. Therefore, if drugs contain hydrazine hydrate and hydrazine compound residues, drugs will have quality defects and pose a threat to human health. It is particularly important to establish a rapid, sensitive, accurate and reliable analytical method to control the content of hydrazine hydrate and hydrazine compounds in drugs in the development process of human medicine.

According to the analysis of the current market situation of China's hydrazine hydrate industry in 2020, the production process of dioxygen water method has great potential

1、 Hydrazine hydrate industry chain.Hydrazine, also known as hydrazine, is the simplest diamine, which can form stable hydrazine hydrate with water. Hydrazine hydrate is a colorless and transparent oily liquid with light ammonia smell. It has strong polarity, reducibility, alkalinity and hygroscopicity. It is an important chemical raw material and chemical raw material

Treatment method of hydrazine hydrate production wastewater

The pollutants in hydrazine hydrate production wastewater are expressed in the form of COD, ammonia nitrogen and salinity. Therefore, the current treatment methods of hydrazine hydrate production wastewater are mainly aimed at these three kinds of pollutants. In addition, hydrazine hydrate is a specific project in the surface water source of centralized domestic and drinking water, so the degradation and removal of hydrazine hydrate in wastewater is also very important. Due to local differences, the treatment requirements and discharge standards of hydrazine hydrate production wastewater from different enterprises are also different: if the municipal pipe network in the industrial zone or non industrial zone is perfect, it only needs to be treated to meet the takeover standard of the local urban sewage plant; If there is no municipal pipe network in the industrial or non industrial area and the effluent needs to be directly discharged, it needs to be treated to meet the direct discharge standard.
