2-Bromo-4'-nitroacetophenone Chemical Properties,Usage,Production

Chemical Properties

yellow to orange crystalline powder

Uses

2-Bromo-4′-nitroacetophenone was used to study the pKa of the histidine-34 imidazole.

Synthesis Reference(s)

Synthesis, p. 487, 1980 DOI: 10.1055/s-1980-29067

Synthesis

940-13-6

99-81-0

The general procedure for the synthesis of 2-bromo-4'-nitroacetophenone using the compound (CAS: 940-13-6) as starting material: haloalkynes (0.5 mmol), AgF (5 mol%), and water (1 eq.) were dissolved in trifluoroacetic acid (TFA, 1 mL), and the reaction was stirred for 6 hr at 40 °C. Upon completion of the reaction, TFA was recovered by distillation for reuse. The residue was purified by column chromatographic separation to afford the target product 2-bromo-4'-nitroacetophenone in pure form.

Purification Methods

Crystallise it from *C6H6/pet ether. [Beilstein 7 IV 661.]
