Cimetidine impurity 26 CAS 208447-53-4

Description

Under current pharmacopoeial and regulatory frameworks, quality-control requirements for this class of reference material explicitly involve the control of targets including Cimetidine impurity 26.

CATO supplies Cimetidine impurity 26 (CAS 208447-53-4), a pharmacopoeial impurity reference standard (molecular formula C11H20N8S2, MW 328.46 g/mol) used for the identification and quantification of trace impurities in APIs.

Cimetidine impurity 26 (C11H20N8S2) contains a nitrogen-containing heterocyclic scaffold, a nitrile group, sulfur-containing functionality. Its physicochemical properties are representative of its class; these physicochemical properties determine the optimal preparation and storage of its standard solutions. 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.

As a certified reference material (CRM), Cimetidine impurity 26 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.
