Abstract
The present study reports the degradation behavior of hydroxychloroquine (HCQ) under the conditions of hydrolysis (acid, alkali and water), oxidation (30% H 2 O 2 ), dry heat and photolysis (UV-VIS light) in accordance with the ICH guidelines. HCQ and all six degradation products formed under alkaline photolytic conditions were optimally resolved on an XTerra茂驴陆 RP18 column with mobile phase composed of methanol, acetonitrile and ammonium formate buffer (20mM, pH 4.5) in an isocratic mode. The drug was stable in all other forced condition. The products were characterized through +ESI-MS n and LC-ESI-MS- TOF and LC-PDA data of the drug as well as degradation products. The products I-IV were characterized as N-oxide HCQ, dechlorinated HCQ, N-desethylated HCQ and N-dealkylated HCQ. The product I and VI were not characterized due to limited data. This library of HCQ degradation products provides a foundation for further product development and stability monitoring.Biography
