A dihalogenated acetophenone building block

As a synthesis intermediate for APIs, chalcone derivatives and carbazole derivatives

Specifications | MSDS | Literature and Reviews

3′-Bromo-4′-fluoroacetophenone (CAS number 1007-15-4) is an acetophenone derivative featuring meta-bromide and para-fluoride function groups. Para/meta-substituted acetophenones have shown antimicrobial activity with inhibitory concentration as low as 246 µM. 3′-Bromo-4′-fluoroacetophenone is applied as a precursor for the synthesis of chalcone, an α,β-unsaturated ketone that is utilised in drug discovery, liquid crystals and optical materials.

3′-Bromo-4′-fluoroacetophenone is also a precursor for an acetyl-functionalised carbazole through a tandem Suzuki-coupling/SNAr approach.
