Chemical Structure
Description
Compared with other compounds in its class, the molecular weight of 524.99 g/mol gives Pemafibrate Impurity 88 distinctive chromatographic separation conditions and mass-spectrometry parameter settings.
CATO supplies Pemafibrate Impurity 88 (CAS CATO-C4X-290388), a pharmacopoeial impurity reference standard (molecular formula C28H29ClN2O6, MW 524.99 g/mol) used for the identification and quantification of trace impurities in APIs.
Pemafibrate Impurity 88 (C28H29ClN2O6) contains a steroid core, an amide group, a hydroxyl group, an ether linkage, chlorine substitution. It is notably hygroscopic, halogen substitution raises its density and boiling point, the carboxyl group imparts weak acidity; these physicochemical properties determine the optimal preparation and storage of its standard solutions. The aromatic system may exhibit native fluorescence, enabling detection with a fluorescence detector (FLD).
Recommended for quantitative analysis by HPLC, GC, LC-MS/MS, or GC-MS as an external calibration standard; it can also be used for spiked-recovery experiments, LOD/LOQ determination, and LC-MS/MS multiple-reaction-monitoring (MRM) calibration.
The assigned purity is verified by mass-balance and quantitative NMR (qNMR) approaches, with the expanded uncertainty reported at a 95% confidence level (k=2). Batch homogeneity and stability are independently assessed for every lot.
