Benzoyl peroxide assay using high-pressure liquid chromatography

A highly specific assay for benzoyl peroxide was developed using high-pressure liquid chromatography. A concentration curve was recorded from 0.1 to 3.0 microgram with a correlation coefficient of 0.9969. The standard deviation for 10 individual analyses of a benzoyl peroxide preparation was +/- 0.547 (1.80% RSD).
