Chemical Structure
Description
Compared with other compounds in its class, the molecular weight of 790.90 g/mol gives Fluticasone Impurity 100 distinctive chromatographic separation conditions and mass-spectrometry parameter settings.
Fluticasone Impurity 100 (CAS 2408725-66-4) is a certified pharmaceutical impurity reference standard with the molecular formula C42H50F4O8S and a molecular weight of 790.90 g/mol.
Fluticasone Impurity 100 (C42H50F4O8S) contains a sulfone group, a carboxylic acid group, a hydroxyl group, an ether linkage, fluorine substitution, a polycyclic aromatic system. 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.
CATO manufactures Fluticasone Impurity 100 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.
