Abstract
Sertraline hydrochloride is an antidepressant of the selective serotonin reuptake inhibitor (SSRI) class, is synthesized for commercial use as a drug substance in highly pure form. During the synthetic process development studies of Sertraline hydrochloride, an impurity was detected in the final product at levels ranging from 0.05% to 0.15% in Gas Chromatography (GC) method and its molecular weight was determined by LC-MS analysis. The impurity was identified as 4-(4-chlorophenyl)-3,4-dihydronaphthalen-1(2H)-ol impurity, synthesized and characterized, the process of its formation was discussed in detail. After qualification of impurity standard, it was used as a reference standard for development of quantification by High Performance Liquid Chromatography (HPLC) method.
