TCI B6800 (CAS 23489-36-3) is 1-(benzofuran-2-yl)-2-bromoethan-1-one, a reactive alpha-bromoketone built on a benzofuran core. It is a standard partner for Hantzsch thiazole synthesis and for one-step condensations toward imidazoles and imidazopyridines. The compound also acts as an efficient alkylating agent for sulfur, nitrogen, and oxygen nucleophiles in multi-step routes. Because alpha-bromoketones are lachrymatory and strongly alkylating, always handle this TCI reagent in a fume hood with full personal protective equipment.
