Application

1.It is used in the synthesis of pesticide insecticide and acaricide monometamidine and bimetamidine. 

2.It is also used in the production of medicine, synthetic leather, artificial leather and chemical fiber textile solvent.

Storage

Sealed storage to prevent leakage, avoid rain, exposure, severe impact and friction.

Keep away from fire and heat sources.

Stability

1. Colorless transparent viscous oily liquid.
It is soluble in water and can also dissolve inorganic salts.
It is hygroscopic and easily decomposes in acidic or alkaline solutions.
It smells of ammonia.

The chemical properties interact with hydrogen chloride to form two kinds of salts;
HCONHCH3·HCl is produced in non-polar solvents;
(HCONHCH3)2·HCl is produced without solvents.
It has almost no effect with sodium metal at room temperature.
Hydrolysis occurs under the action of acid or alkali.
The acidic hydrolysis rate is formamide>N-methylformamide>N,N-dimethylformamide.
The alkaline hydrolysis rate is formamide-N-methylformamide>N,N-dimethylformamide.

2. Exist in mainstream smoke.
