Compared with other compounds in its class, the molecular weight of 379.46 g/mol gives Baxdrostat Impurity 22 distinctive chromatographic separation conditions and mass-spectrometry parameter settings.
CATO supplies Baxdrostat Impurity 22 (CAS 1428652-32-7), a pharmacopoeial impurity reference standard (molecular formula C22H25N3O3, MW 379.46 g/mol) used for the identification and quantification of trace impurities in APIs.
Baxdrostat Impurity 22 (C22H25N3O3) contains a steroid core, an amide group, a hydroxyl group, an ether linkage. It is notably hygroscopic, the carboxyl group imparts weak acidity; these physicochemical properties determine the optimal preparation and storage of its standard solutions. Nitrogen-containing functional groups confer excellent ionization efficiency in positive-ion electrospray (ESI) mode, making the compound well suited to LC-MS/MS analysis.
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.
