HPLC - MS Method for Analysis of Mupirocin on Newcrom BH Column by SIELC Technologies
Description
· High Performance Liquid Chromatography (HPLC) Method for Analysis of Mupirocin .
Mupirocin is an antibiotic ointment with the chemical formula C 26 H 44 O 9 . Commonly prescribed for skin infections caused by Staphylococcus and Streptococcus bacteria. It is effective against both methicillin-sensitive Staphylococcus aureus (MSSA) and methicillin-resistant Staphylococcus aureus (MRSA). It is also used to eliminate nasal colonization of MRSA in some healthcare settings. Mupirocin works by inhibiting the bacterial enzyme isoleucyl-tRNA synthetase. This disruption prevents the bacteria from making necessary proteins, leading to its death.
Mupirocin can be retained, separated, and analyzed on a mixed-mode Newcrom BH column with a mobile phase consisting of water, Acetonitrile (MeCN), and Ammonium Formate. This analytical method can be detected with high resolution and peak symmetry with many evaporative detection methods, including Evaporative Light Scattering Detection (ELSD), Charged Aerosol Detector (CAD), and Electrospray Ionization (ESI) for Mass Spectrometry (MS).
