Cimetidine EP Impurity E CAS 54237-72-8

Description

The occurrence of Cimetidine EP Impurity E is closely related to a nitrogen-containing heterocyclic scaffold, an amide group, sulfur-containing functionality, a hydroxyl group, an ether linkage in its molecular formula, which determines its behaviour during synthesis, purification, or degradation.

CATO supplies Cimetidine EP Impurity E (CAS 54237-72-8), a pharmacopoeial impurity reference standard (molecular formula C10H16N6OS, MW 268.34 g/mol) used for the identification and quantification of trace impurities in APIs.

Based on its molecular formula C10H16N6OS, Cimetidine EP Impurity E contains a nitrogen-containing heterocyclic scaffold, an amide group, sulfur-containing functionality, a hydroxyl group, an ether linkage; these features give the compound characteristic absorption bands in UV spectroscopy. The molecular weight of 268.34 g/mol is directly relevant to the identification of the molecular ion in mass spectrometry. The aromatic system may exhibit native fluorescence, enabling detection with a fluorescence detector (FLD).

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 Cimetidine EP Impurity E 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.
