Chemical Structure
Description
Compared with other compounds in its class, the molecular weight of 435.48 g/mol gives Fluticasone Impurity 84 distinctive chromatographic separation conditions and mass-spectrometry parameter settings.
As a process- or degradation-related impurity, Fluticasone Impurity 84 (CAS CATO-C4X-165084, N/A) is essential for impurity profiling, related-substances testing, and forced-degradation studies in pharmaceutical development.
Fluticasone Impurity 84 is supplied as a fully characterized reference material; its structural identity, assigned purity, and stability data are documented in the batch-specific Certificate of Analysis (COA).
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.
