Benzoic acid, 4-hydrazino-, ethyl ester - Introduction

Ethyl hydrazinobenzoate, also known as ethyl N-benzylphenylhydrazinecarboxylate, is an organic compound.

Nature:
Ethyl hydrazinobenzoate is a colorless liquid with a special ammonia odor. Its molecular formula is C9H12N2O2 and its molecular weight is 180.21. It has a boiling point of about 230 degrees Celsius and a density of about 1.10 g/cm ^ 3. At room temperature can be dissolved in most organic solvents, but insoluble in water.

Use:
Ethyl hydrazinobenzoate is mainly used for the synthesis of pharmaceuticals and plant protection products. It can be used as an intermediate in the synthesis of oxime antibiotics and as a precursor for the synthesis of anticancer drugs. In addition, it can also be used in the synthesis of heterocyclic compounds and dyes.

Method:
The preparation of ethyl hydrazinobenzoate is generally obtained by reacting hydrazide with ethyl benzanoate. The specific method is to react hydrazide with ethyl benzanoate under alkaline conditions to obtain ethyl hydrazinobenzoate.

Safety Information:
Ethyl hydrazinobenzoate is dangerous. It is a flammable liquid that may cause combustion in case of open flame or high temperature. During storage and use, care should be taken to avoid contact with oxidants and other combustibles. In the laboratory, when using ethyl hydrazinobenzoate, wear appropriate personal protective equipment, such as protective glasses and gloves. Also pay attention to a well-ventilated operating environment and follow correct operating procedures. In case of contact with skin or eyes, rinse immediately with plenty of water and seek medical help.
