HPLC Analysis of Drug Prozac and Related Impurities on Heritage MA Mixed-Mode Column

Application description

Fluoxetine (Prozac) is an antidepressant of the selective serotonin reuptake inhibitor(SSRI) class. It is used for the treatment of major depressive disorder, obsessive-compulsive disorder (OCD), bulimia nervosa, panic disorder and premenstrual dysphoric disorder. Fluoxetine is hydrophobic and basic in nature. Fluoxetine and related impurities were analyzed by mixed-mode chromatography on Heritage MA HPLC column. Compounds are separated by reversed-phase and cation-exclusion mechanisms. Retention time, selectivity, and resolution between peaks can be adjusted by modification of amount of ACN, buffer and buffer pH. Various mobile phases can be used with Heritage MA column to accommodate different detection techniques (UV, MS, CAD, ELSD detection).
