Famotidine Impurity 30 CAS CATO-C4X-139231

Description

Compared with other compounds in its class, the molecular weight of 231.30 g/mol gives Famotidine Impurity 30 distinctive chromatographic separation conditions and mass-spectrometry parameter settings.

CATO supplies Famotidine Impurity 30 (CAS CATO-C4X-139231), a pharmacopoeial impurity reference standard (molecular formula C6H9N5OS2, MW 231.30 g/mol) used for the identification and quantification of trace impurities in APIs.

Owing to an amide group, sulfur-containing functionality, a hydroxyl group, an ether linkage, an aromatic ring system, Famotidine Impurity 30 is typically off-white to pale yellow crystalline powder. Its solid-state physicochemical attributes — including a molecular weight of 231.30 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.
