Chemical Structure
Description
As a certified reference material (CRM), Fluticasone Impurity 113 meets the metrological traceability requirements of ISO/IEC 17025 laboratories. Batch-to-batch consistency is monitored via control charts to guarantee comparable assigned values across lots.
CATO supplies Fluticasone Impurity 113 (CAS CATO-C4X-1650113), a pharmacopoeial impurity reference standard (molecular formula C26H28ClFO6S, MW 523.01 g/mol) used for the identification and quantification of trace impurities in APIs.
Owing to a steroid core, a sulfone group, a hydroxyl group, an ether linkage, fluorine/chlorine substitution, Fluticasone Impurity 113 is typically pale yellow to yellow crystalline powder. Its solid-state physicochemical attributes — including a molecular weight of 523.01 g/mol — guide the selection of appropriate sample preparation and analytical techniques. Halogen substitution (F/Cl/Br/I) produces a distinctive isotope pattern in mass spectrometry, a valuable aid for qualitative confirmation.
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.
