Famotidine impurity 76 CAS CATO-C4X-139276 chemical structure

Description

CATO manufactures Famotidine impurity 76 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.

Famotidine impurity 76 (CAS CATO-C4X-139276) is a certified pharmaceutical impurity reference standard with the molecular formula C2H3N3O and a molecular weight of 85.06 g/mol.

Famotidine impurity 76 (C2H3N3O) contains an amide group, a hydroxyl group, an ether linkage. Its physicochemical properties are representative of its class; these physicochemical properties determine the optimal preparation and storage of its standard solutions. The presence of an aromatic ring or conjugated system gives the compound characteristic absorption bands in the UV-Vis region, making it well suited to UV or diode-array detection (DAD).

Recommended for quantitative analysis by HPLC, GC, LC-MS/MS, or GC-MS as an external calibration standard; it can also be used for spiked-recovery experiments, LOD/LOQ determination, and LC-MS/MS multiple-reaction-monitoring (MRM) calibration.
