Description
CATO manufactures Mometasone Furoate EP Impurity O 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.
Mometasone Furoate EP Impurity O (CAS 24916-91-4) is a certified pharmaceutical impurity reference standard with the molecular formula C24H31ClO6 and a molecular weight of 450.95 g/mol.
Mometasone Furoate EP Impurity O (C24H31ClO6) contains a flavonoid core, a hydroxyl group, an ether linkage, chlorine substitution. 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. Halogen substitution (F/Cl/Br/I) produces a distinctive isotope pattern in mass spectrometry, a valuable aid for qualitative confirmation.
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.
