Famotidine Impurity 80 CAS CATO-C4X-139280 chemical structure

Description

As a certified reference material (CRM), Famotidine Impurity 80 meets the metrological traceability requirements of ISO/IEC 17025 laboratories. Batch-to-batch consistency is monitored via control charts to guarantee comparable assigned values across lots.

CATO supplies Famotidine Impurity 80 (CAS CATO-C4X-139280), a pharmacopoeial impurity reference standard (molecular formula C3H8N2O4S, MW 168.17 g/mol) used for the identification and quantification of trace impurities in APIs.

Based on its molecular formula C3H8N2O4S, Famotidine Impurity 80 contains an amide group, a sulfone group, a carboxylic acid group, an ether linkage; these features give the compound characteristic functional-group stretching vibrations in infrared spectroscopy. The molecular weight of 168.17 g/mol is directly relevant to the identification of the molecular ion in mass spectrometry. 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.
