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 Hydrocortisone Impurity 51.
Hydrocortisone Impurity 51 (CAS CATO-C4X-140151) is a certified pharmaceutical impurity reference standard with the molecular formula C23H30O6 and a molecular weight of 402.48 g/mol.
Owing to a flavonoid core, a hydroxyl group, an ether linkage, Hydrocortisone Impurity 51 is typically pale yellow to yellow crystalline powder. Its solid-state physicochemical attributes — including a molecular weight of 402.48 g/mol — guide the selection of appropriate sample preparation and analytical techniques. 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 Hydrocortisone Impurity 51 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.
