Fluticasone Propionate EP Impurity F CAS 1219174-94-3

Description

Compared with other compounds in its class, the molecular weight of 498.55 g/mol gives Fluticasone Propionate EP Impurity F distinctive chromatographic separation conditions and mass-spectrometry parameter settings.

CATO supplies Fluticasone Propionate EP Impurity F (CAS 1219174-94-3), a pharmacopoeial impurity reference standard (molecular formula C25H29F3O5S, MW 498.55 g/mol) used for the identification and quantification of trace impurities in APIs.

Structurally, Fluticasone Propionate EP Impurity F (C25H29F3O5S) contains a flavonoid core, a sulfone group, a hydroxyl group, an ether linkage, fluorine substitution. The molecule exhibits a degree of unsaturation (DBE) of 10.0, corresponding to approximately 10 ring(s) or double-bond equivalent(s). With a molecular weight of 498.55 g/mol, it falls into the moderately-high-molecular-weight range. 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.

The assigned purity is verified by mass-balance and quantitative NMR (qNMR) approaches, with the expanded uncertainty reported at a 95% confidence level (k=2). Batch homogeneity and stability are independently assessed for every lot.
