It is an α-bromoketone-aldehyde.[1] Coupling of 1-bromopinacolone with various aldehyde electrophiles catalyzed by SmI2 has been reported.It acts as reversible competitive inhibitor for acetylcholinesterase, during hydrolysis of acetylcholine.It is the suitable reagent for the synthesis of a photolabile azido derivative of the kaurene oxidase inhibitor 1-(4- chlorophenyl)4,4-dimethyl-2-(1,2,4-triazol-1-yl) pentan-3-ol (paclobutrazol).It may be used as reagent in the synthesis of 2-t-butyl-6-benzoylimidazo[1,2-b]pyridazine. 1-Bromopinacolone is an α-bromoketone-aldehyde.
