Toxicological data

1, acute toxicity: mice (peritoneal) LD50: 65mg/kg

Rat (subcutaneous)LD50: 120mg/kg

Since the LD50 of table salt is 3,000 mg/kg, the acute toxicity of BPA is the same as that of table salt.

Ecological data

For products that are slightly harmful to water, do not let large amounts of products come into contact with groundwater, waterways or sewage systems. Do not discharge materials into the surrounding environment without government permission.

Properties and stability

Keep away from oxides and moisture.

Storage method

Store in an airtight container in a cool, dry place. The storage place must be away from oxidants and water sources. Avoid contact with moisture and water.

Synthesis method

It is obtained by the reaction of ethyl formate and hydrazine hydrate. Carefully add 85% hydrazine hydrate to the solution of ethyl formate and 95% ethanol, and stir for 10 minutes. When the reaction eases, the reaction solution is heated to reflux for 18 hours, and most of the water and ethanol are evaporated under reduced pressure to obtain crude syrupy product, which is further refined to obtain the finished product of carboxyl hydrazide.
