Pidotimod Impurity N10 CAS 72744-67-3

Description

Compared with other compounds in its class, the molecular weight of 230.31 g/mol gives Pidotimod Impurity N10 distinctive chromatographic separation conditions and mass-spectrometry parameter settings.

CATO supplies Pidotimod Impurity N10 (CAS 72744-67-3), a pharmacopoeial impurity reference standard (molecular formula C8H10N2O2S2, MW 230.31 g/mol) used for the identification and quantification of trace impurities in APIs.

Pidotimod Impurity N10 (C8H10N2O2S2) contains a nitrogen-containing heterocyclic scaffold, an amide group, a sulfone 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. 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.
