Chemical Structure

Famotidine Impurity 88 CAS CATO-C4X-139288 chemical structure

Description

Famotidine Impurity 88 (C8H13N7OS2) contains a nitrogen-containing heterocyclic scaffold, an amide group, sulfur-containing functionality, 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. Nitrogen-containing functional groups confer excellent ionization efficiency in positive-ion electrospray (ESI) mode, making the compound well suited to LC-MS/MS analysis.

Famotidine Impurity 88 (CAS CATO-C4X-139288) is a certified pharmaceutical impurity reference standard with the molecular formula C8H13N7OS2 and a molecular weight of 287.37 g/mol.

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.

As a certified reference material (CRM), Famotidine Impurity 88 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.
