Trimethylamine 40% w/w aqueous solution is a colorless, strongly basic and pungent-smelling liquid used primarily in the synthesis of pharmaceuticals, agrochemicals, and as a reagent in organic chemistry. It serves as a precursor in quaternary ammonium compound production, notably choline chloride, and is also employed in the manufacture of rubber accelerators and textile treatments. This aqueous solution has a CAS number of 75-50-3, with the molecular formula (CH3)3N and a molecular weight of 59.11. It must be stored at ambient conditions, and it carries a Signal Word of Danger due to its hazardous properties. Molekula supplies Trimethylamine 40% w/w aqueous solution from research to bulk quantities with full documentation and ISO 9001:2015 traceability.
