Chemical Structure

Tizanidine Nitroso Impurity 14 CAS CATO-C4X-144514 chemical structure

Description

The occurrence of Tizanidine Nitroso Impurity 14 is closely related to a nitrogen-containing heterocyclic scaffold, an amide group, a sulfone group, a hydroxyl group, an ether linkage, chlorine substitution in its molecular formula, which determines its behaviour during synthesis, purification, or degradation.

CATO supplies Tizanidine Nitroso Impurity 14 (CAS CATO-C4X-144514), a pharmacopoeial impurity reference standard (molecular formula C9H6ClN7O2S, MW 311.71 g/mol) used for the identification and quantification of trace impurities in APIs.

Tizanidine Nitroso Impurity 14 (C9H6ClN7O2S) contains a nitrogen-containing heterocyclic scaffold, an amide group, a sulfone group, a hydroxyl group, an ether linkage, chlorine substitution. It is notably hygroscopic, halogen substitution raises its density and boiling point, the carboxyl group imparts weak acidity; these physicochemical properties determine the optimal preparation and storage of its standard solutions. 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 Tizanidine Nitroso Impurity 14 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.
