Property

CAS No.: 124-40-3 Formula: C2H7N Molecular Weight: 45.08370

Description

Dimethylamine is an organic compound with the formula (CH3)2NH. This secondary amine is a colorless, flammable gas with an ammonia-like odor. Dimethylamine is commonly encountered commercially as a solution in water at concentrations up to around 40%. In 2005, an estimated 270,000 tons were produced industrially, but it is also found as a natural product.
