CAS 2857-97-8 — Bromotrimethylsilane

Bromotrimethylsilane (CAS 2857-97-8) is a silane compound widely used as a reducing agent in organic synthesis, particularly for converting carboxylic acids, esters, and amides into alcohols or aldehydes under mild conditions. It is also employed in the selective reduction of functional groups without affecting other sensitive moieties like double bonds or ketones. This reagent has a molecular weight of 199.14 g/mol (not 132.1146, which corresponds to oxalic acid) and requires storage under inert atmosphere (typically argon or nitrogen) to prevent moisture-induced degradation. It carries no hazard classification under standard GHS criteria, though proper handling in a fume hood is advised due to its reactivity. Molekula supplies Bromotrimethylsilane from research to bulk quantities with full documentation and ISO 9001:2015 traceability.
