Description
CATO supplies Azilsartan Impurity 182 (CAS CATO-C4X-1096182), a pharmacopoeial impurity reference standard (molecular formula C28H26N4O5, MW 498.53 g/mol) used for the identification and quantification of trace impurities in APIs.
Owing to a steroid core, an amide group, a hydroxyl group, an ether linkage, Azilsartan Impurity 182 is typically pale yellow to yellow crystalline powder. Its solid-state physicochemical attributes — including a molecular weight of 498.53 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).
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.
