Trimethylamine is a tertiary amine that is ammonia in which each hydrogen atom is substituted by an methyl group. It has a role as a human xenobiotic metabolite and an Escherichia coli metabolite. Trimethylamine, anhydrous appears as a colorless gas with a fishlike odor at low concentrations changing to ammonia-like odor at higher concentrations. Shipped as a liquid under its own vapor pressure. Contact with the unconfined liquid can cause frostbite from evaporative cooling or chemical type burns.
