Description
Famotidine Impurity 87 (CAS CATO-C4X-139287) is a certified pharmaceutical impurity reference standard with the molecular formula C6H14N6O4S2 and a molecular weight of 298.34 g/mol.
Owing to an amide group, a sulfone group, a carboxylic acid group, a hydroxyl group, an ether linkage, Famotidine Impurity 87 is typically white to pale yellow crystalline powder. Its solid-state physicochemical attributes — including a molecular weight of 298.34 g/mol — guide the selection of appropriate sample preparation and analytical techniques. 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.
CATO manufactures Famotidine Impurity 87 under ISO 17034:2016 accreditation with dual CNAS and ANAB accreditation. Each batch is characterized by orthogonal methods and supplied with a full Certificate of Analysis (COA), ensuring metrological traceability.
