Trimethylamine

Trimethylamine (CAS 75-50-3), commonly abbreviated as TMA, is a tertiary amine supplied primarily in anhydrous form for industrial and specialty chemical applications. It functions as a key intermediate and reactant across pharmaceutical synthesis and food-grade flavoring.

Its strong fishy odor profile is both a target compound and a process marker in various manufacturing sectors. FEMA 3241 status confirms its recognized standing as a flavoring substance in regulated food applications.

In food and flavor manufacturing, TMA is used as a reference and active flavoring agent in seafood-type flavor systems. In these environments, its characteristic odor must be precisely controlled or replicated for consistency.

Pharmaceutical producers use it as a building block in the synthesis of choline salts and quaternary ammonium compounds. Both of these appear frequently in finished drug formulations and nutritional supplements.

It also functions as a catalyst and intermediate in the production of ion exchange resins and specialty chemicals. In preservation-related applications, TMA derivatives contribute to biocidal formulations targeting microbial control.

Trimethylamine is supplied as a compressed anhydrous gas or as aqueous solution, typically at concentrations of 30 to 45 percent in water. Food-grade and technical-grade designations are the most commonly available specifications.

Packaging ranges from pressurized cylinders for anhydrous supply to drum quantities for aqueous grades. This ensures safe handling and transport according to the specific requirements of the industrial or laboratory facility.
