Chemical Structure
Description
Under current pharmacopoeial and regulatory frameworks, quality-control requirements for this class of reference material explicitly involve the control of targets including Methylprednisolone Acetate EP Impurity A (Mixture of Diastereomers).
Methylprednisolone Acetate EP Impurity A (Mixture of Diastereomers) (CAS 151003-82-6) is a certified pharmaceutical impurity reference standard with the molecular formula C24H34O6 and a molecular weight of 418.52 g/mol.
Methylprednisolone Acetate EP Impurity A (Mixture of Diastereomers) (C24H34O6) 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 presence of an aromatic ring or conjugated system gives the compound characteristic absorption bands in the UV-Vis region, making it well suited to UV or diode-array detection (DAD).
This reference standard supports related-substances testing and method development in line with ICH Q3A/Q3B guidance on impurity control, and is suitable for system suitability testing and forced-degradation studies.
CATO manufactures Methylprednisolone Acetate EP Impurity A (Mixture of Diastereomers) 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.
