Trimethylamine

Trimethylamine (CAS 75-50-3, EC 200-875-0), also known as NMe3 or N(CH3)3, is a tertiary amine with the molecular formula C3H9N. It carries no assigned E-code for direct food use but is recognized under FEMA 3241 as a flavoring substance in regulated applications.

In food and flavor manufacturing, trimethylamine contributes characteristic fishy and ammoniacal notes at trace concentrations, functioning as a reference standard and flavorant in controlled formulations. In pharmaceutical and industrial contexts, it serves as a precursor in synthesizing choline salts and quaternary ammonium biocides, where its nucleophilic nitrogen drives the alkylation reaction.

Trimethylamine is supplied as a compressed gas or in aqueous solution, with grades available to meet FCC and REACH compliance requirements. Procurement teams should confirm grade specification, concentration, and cylinder or bulk liquid formats with the supplier prior to ordering, as handling classifications vary by form.
