Description
Dimethylamine (CAS 124-40-3, EC 204-697-4) is a secondary amine with the formula C2H7N, commercially available as aqueous solutions under designations such as DMA-40, DMA-60, and DMA-65, referring to their respective concentration levels. It carries no E-code designation and is classified under HS code 29211100.
In food and nutrition manufacturing, dimethylamine functions as a flavorant precursor, contributing to characteristic fishy or roasted notes in controlled concentrations through its reactivity with carbonyl compounds in Maillard-type pathways. It also serves as a pH-adjusting agent in certain acidulant applications, where its basicity enables precise buffering in aqueous food systems.
Dimethylamine is supplied as aqueous solutions at concentrations of 40%, 60%, and 65% w/w, with food-contact grades conforming to FCC specifications. Procurement must account for REACH registration obligations and applicable CLP classification for corrosive and flammable substances. Packaging typically includes IBC containers and road tankers for bulk supply.
