NOVEL METHOD FOR DETERMINATION OF POMALIDOMIDE IN HUMAN PLASMA BY ULTRA PERFORMANCE LIQUID CHROMATOGRAPHY MASS SPECTROSCOPY / MASS SPECTROSCOPY

The current investigation studied and verified an accurate Ultra performance liquid chromatography mass spectroscopy/ mass spectroscopy technique for the high-throughput detection of pomalidomide in human plasma with celecoxib as an internal standard. Chromatographic studies were carried out on Hypersil BDS (50 mm x 4.1 mm, 5m) with an isocratic mobile phase of acetonitrile: ammonium formate (80:20, V/V), at a flow rate of 0.5 mL min-1 and a total run time of 3 min. A triple quadruple Tandem Mass spectroscopy with electrospray ionization in positive mode was utilized to identify the analyte. Using multiple reaction monitoring modes and precursor-to-product ion transitions of 274.43 m/z for pomalidomide and 382.12 m/z for standard, respectively, pomalidomide and internal standard were measured. The developed technique was verified as per the regulatory standards for bioanalytical procedures validation. Other validation results also match.
