Chemical Structure
Description
Compared with other compounds in its class, the molecular weight of 612.51 g/mol gives Apalutamide Impurity 107 distinctive chromatographic separation conditions and mass-spectrometry parameter settings.
CATO supplies Apalutamide Impurity 107 (CAS CATO-C4X-2749107), a pharmacopoeial impurity reference standard (molecular formula C29H21F5N6O4, MW 612.51 g/mol) used for the identification and quantification of trace impurities in APIs.
Apalutamide Impurity 107 (C29H21F5N6O4) contains a steroid core, an amide group, a hydroxyl group, an ether linkage, fluorine substitution. It is notably hygroscopic, halogen substitution raises its density and boiling point, 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.
