Chemical Structure
Description
The occurrence of Famotidine Impurity 53 is closely related to a nitrile group, sulfur-containing functionality, iodine substitution in its molecular formula, which determines its behaviour during synthesis, purification, or degradation.
CATO supplies Famotidine Impurity 53 (CAS CATO-C4X-139253), a pharmacopoeial impurity reference standard (molecular formula C5H7IN4S, MW 282.11 g/mol) used for the identification and quantification of trace impurities in APIs.
Famotidine Impurity 53 (C5H7IN4S) contains a nitrile group, sulfur-containing functionality, iodine substitution. Halogen substitution raises its density and boiling point; these physicochemical properties determine the optimal preparation and storage of its standard solutions. Halogen substitution (F/Cl/Br/I) produces a distinctive isotope pattern in mass spectrometry, a valuable aid for qualitative confirmation.
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 53 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.
