How is 2-Bromo-1-phenyl-1-pentanone CAS: 49851-31-2 formulated?

At room temperature, add 16.2 g (0.1 mol) valerophenone and 30.9 g (0.3 mol) sodium bromide to a 500 mL round-bottomed flask, stir well, then add 24 g (0.2 mol) 30% hydrochloric acid, slowly drop Add 19 g (0.15 mol) of 30% hydrogen peroxide, and continue to react for 1 to 2 h. After TLC monitoring is completed, stop stirring, let stand for stratification, and use saturated sodium carbonate and saturated brine respectively. After washing, the organic phases were combined, concentrated, and dried over anhydrous magnesium sulfate to obtain 2-Bromo-1-phenyl-1-pentanone CAS: 49851-31-2 as a bright yellow oily liquid with a yield of 95% and a purity of 98 % (HPLC method).
