Application

Trimethylamine (TMA) has been used in the preparation of poly[9,9′-bis(6′-N,N,N-trimethylammonium)hexyl)fluorene-co-alt-4,7-(2,1,3-benzothiadiazole) dibromide] (PFBT), a water-soluble, cationic conjugated polymer used in label-free DNA microarrays. It can also be used to prepare benzyltrimethylammonium chloride, which then reacts with sodium ethoxide to form benzyltrimethylammonium ethoxide. The adsorption of TMA on the gold surface of trimethylsilylated barium nitrate-gold/titanosilicate catalyst acts as a promoter for the propylene epoxidation with oxygen and hydrogen.

Packaging

Supplied in a Sure/Pac cylinder and has a 316 stainless steel needle valve with a male 1/4" NPTF outlet thread installed . Before using the cylinder, ensure that the valve is closed, then remove the galvanized steel hex cap that seals the outlet valve.

Compatible with the following:
