Chemical Structure
Description
CATO supplies Methylprednisolone Impurity 54 (CAS CATO-C4X-191954), a pharmacopoeial impurity reference standard (molecular formula C24H32O5, MW 400.51 g/mol) used for the identification and quantification of trace impurities in APIs.
Methylprednisolone Impurity 54 (C24H32O5) contains a flavonoid core, a hydroxyl group, an ether linkage. 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.
CATO manufactures Methylprednisolone Impurity 54 under ISO 17034:2016 accreditation with dual CNAS and ANAB accreditation. Each batch is characterized by orthogonal methods and supplied with a full Certificate of Analysis (COA), ensuring metrological traceability.
