Febuxostat Impurity 46 CAS 144060-97-9

Description

Compared with other compounds in its class, the molecular weight of 319.42 g/mol gives Febuxostat Impurity 46 distinctive chromatographic separation conditions and mass-spectrometry parameter settings.

Febuxostat Impurity 46 (CAS 144060-97-9) is a certified pharmaceutical impurity reference standard with the molecular formula C17H21NO3S and a molecular weight of 319.42 g/mol.

Owing to a steroid core, an amide group, a sulfone group, a hydroxyl group, an ether linkage, Febuxostat Impurity 46 is typically pale yellow to yellow crystalline powder. Its solid-state physicochemical attributes — including a molecular weight of 319.42 g/mol — guide the selection of appropriate sample preparation and analytical techniques. The high carbon-to-hydrogen ratio imparts good lipophilicity, allowing liquid-liquid extraction with non-polar solvents such as n-hexane or ethyl acetate.

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 certified reference material (CRM), Febuxostat Impurity 46 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.
