Properties and stability

Avoid contact with strong oxidants and acids.

Storage method

Store in a cool, ventilated warehouse. Keep away from fire and heat sources. The storage temperature should not exceed 30℃. They should be stored separately from oxidants and acids, and avoid mixed storage. Use explosion-proof lighting and ventilation facilities. It is prohibited to use mechanical equipment and tools that are prone to sparks. The storage area should be equipped with emergency release equipment and suitable containment materials.

Synthesis method

It is obtained by hydrolysis, addition and degradation of acrylonitrile; another production method is to obtain this product by hydrogenating ethylenediaminoacetonitrile.

Purpose

It is used in medicine to synthesize procainamide hydrochloride, chloroprocaine hydrochloride, cinchaine hydrochloride, and tiapride hydrochloride. Used as an intermediate in organic synthesis.
