Abstract
A HPLC method was established for the determination of O-methylhydroxylamine hydrochloride. A C18 column was used with the mobile phase of methanol-0.025mol/L potassium dihydrogen phosphate solution(adjusted to pH 3.2 with phosphoric acid) (60∶40) at the detection wavelength of 242nm. The calibration curve was linear in the range of 10 -400μg/ml. The average recovery was above 98.5% and RSDs less than 0.4%.
