Application

1-Bromo-2-butanone (bromomethyl ethyl ketone) was used as a potential regulatory site-directed reagent for the residue C221 on pyruvate decarboxylase. It was also used as a reagent for aromatic bromination with sodium hydride in DMSO and in a microwave-assisted preparation of fused heterocycles.
