Description
Fluocinolone Acetonide Impurity 36 (CAS CATO-C4X-238136) is a certified pharmaceutical impurity reference standard with the molecular formula C25H30ClFO7 and a molecular weight of 496.95 g/mol.
Based on its molecular formula C25H30ClFO7, Fluocinolone Acetonide Impurity 36 contains a flavonoid core, a hydroxyl group, an ether linkage, fluorine/chlorine substitution; these features give the compound characteristic absorption bands in UV spectroscopy. The molecular weight of 496.95 g/mol is directly relevant to the identification of the molecular ion in mass spectrometry. The aromatic system may exhibit native fluorescence, enabling detection with a fluorescence detector (FLD).
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 Fluocinolone Acetonide Impurity 36 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.
