Compared with other compounds in its class, the molecular weight of 486.54 g/mol gives Fluticasone Furoate EP Impurity B distinctive chromatographic separation conditions and mass-spectrometry parameter settings.
CATO supplies Fluticasone Furoate EP Impurity B (CAS 80474-24-4), a pharmacopoeial impurity reference standard (molecular formula C24H29F3O5S, MW 486.54 g/mol) used for the identification and quantification of trace impurities in APIs.
Owing to a flavonoid core, a sulfone group, a hydroxyl group, an ether linkage, fluorine substitution, Fluticasone Furoate EP Impurity B is typically pale yellow to yellow crystalline powder. Its solid-state physicochemical attributes — including a molecular weight of 486.54 g/mol — guide the selection of appropriate sample preparation and analytical techniques. The aromatic system may exhibit native fluorescence, enabling detection with a fluorescence detector (FLD).
Recommended for quantitative analysis by HPLC, GC, LC-MS/MS, or GC-MS as an external calibration standard; it can also be used for spiked-recovery experiments, LOD/LOQ determination, and LC-MS/MS multiple-reaction-monitoring (MRM) calibration.
CATO manufactures Fluticasone Furoate EP Impurity B 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.
