Application description

Bupropion is a medication primarily used as an antidepressant and smoking cessation aid. It is an effective antidepressant on its own, but is also used as an add-on medication in cases of incomplete response to first-line SSRI antidepressants.Common side effects include dry mouth, trouble sleeping, agitation, and headaches. It is a norepinephrine-dopamine reuptake inhibitor (NDRI) and a nicotinic receptor antagonist. It is an atypical antidepressant, different from most others. Bupropion is classified as cathinones and is similar in structure to substituted phenethylamines. Bupropion and related impurities were separated by mixed-mode chromatography without the use of ion-pairing reagents (IP reagent). Compounds are retained on Coresep 100 column by combination of reversed-phase and cation-exchange 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 Coresep 100 column to accommodate various detection techniques (UV, MS, CAD, ELSD detection). Core-shell mixed-mode columns provide a great combination of unique selectivity, speed, and efficiency.
