Isobutyrophenone was used as an internal standard in the determination of hydroxyzine hydrochloride and benzyl alcohol in injection solutions. It was also used in the preparation of alpha-hydroxyisobutyrophenone. | [Uses]
Isobutyrophenone is used as an internal standard in the determination of hydroxyzine hydrochloride and benzyl alcohol in injection solutions. It is also used in the preparation of alpha-hydroxyisobutyrophenone. Isobutyrophenone is employed as photosensitizer intermediate. It can react with bromoacetic acid ethyl ester to get 3-hydroxy-4-methyl-3-phenyl-valeric acid ethyl ester. | [Preparation]
Isobutyrophenone synthesis: Benzene underwent a Friedel–Crafts acylation with isobutyryl chloride to synthesize isobutyrophenone. The reaction was performed using excess benzene as a replacement for a typical solvent and heat to reflux (88 °C) for a period of 3 hours. Any unreacted benzene was recovered after the reaction during the distillation process. A 66 % yield of isobutyrophenone was obtained from the solar synthesis, compared to a 44 % yield from an in-lab, electrical heating analysis.
