Application

Dimethylamine hydrochloride has been used in the preparation of hexamethylmelamine-methyl-14C. It has also been used to prepare the standard solution of methylamine (MA), dimethylamine (DMA), trimethylamine (TMA), and trimethylamine-N-oxide (TMAO) while determing methylamines and trimethylamine-N-oxide in particulate matter.
