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.

New Tariffs & Effects on Pricing

Tariff note: As we navigate the current environment of tariff surcharges and mid-year manufacturer price increases, we want to keep you informed. While we have avoided making specific decisions thus far, we anticipate that we will be forced to implement a cost adjustment policy to offset the fees we have already been absorbing. We are committed to transparency and moderation in this process.
