Chemical Structure

Famotidine EP Impurity C CAS 106433-44-7 chemical structure

Description

Compared with other compounds in its class, the molecular weight of 338.43 g/mol gives Famotidine EP Impurity C distinctive chromatographic separation conditions and mass-spectrometry parameter settings.

CATO supplies Famotidine EP Impurity C (CAS 106433-44-7), a pharmacopoeial impurity reference standard (molecular formula C8H14N6O3S3, MW 338.43 g/mol) used for the identification and quantification of trace impurities in APIs.

The molecular framework of Famotidine EP Impurity C (C8H14N6O3S3) is characterized by a nitrogen-containing heterocyclic scaffold, an amide group, a sulfone group, a hydroxyl group, an ether linkage. In reversed-phase chromatography, its retention is governed primarily by the protonation state of its nitrogen-containing groups, which provides a practical basis for HPLC-UV/DAD or LC-MS method development. 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).

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 EP Impurity C 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.
