HPLC Method for Determination of Azithromycin on Primesep 200 Column
High Performance Liquid Chromatography (HPLC) Method for Analysis of Azithromycin .
Azithromycin is an antibiotic with the chemical formula C38H72N2O12 . It is used in the treatment of various bacterial infections including but not limited to pneumonia, strep throat, and STI. As a medication, it is available in a variety of forms: tablets, capsules, injections, and solutions. It is on the WHOs list of essential medicines and is classified as critically important.
In reversed-phase HPLC, it generally exhibits significant tailing. The tailing can be substantially reduced by using a mixed-mode Primesep 200 column with a simple MS-compatible mobile phase of water, acetonitrile (ACN) and ammonium formate (AmFm) buffer.
