Chemical Structure
Description
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.
As a process- or degradation-related impurity, Vilanterol Impurity 85 (CAS CATO-C4X-193585, C24H39NO4) is essential for impurity profiling, related-substances testing, and forced-degradation studies in pharmaceutical development.
Owing to a steroid core, an amide group, a hydroxyl group, an ether linkage, Vilanterol Impurity 85 is typically off-white to pale yellow crystalline powder. Its solid-state physicochemical attributes — including a molecular weight of 405.57 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).
As a certified reference material (CRM), Vilanterol Impurity 85 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.
