Chemical Structure
Description
Compared with other compounds in its class, the molecular weight of 176.20 g/mol gives Tizanidine Impurity 46 distinctive chromatographic separation conditions and mass-spectrometry parameter settings.
As a process- or degradation-related impurity, Tizanidine Impurity 46 (CAS CATO-C4X-144546, C7H4N4S) is essential for impurity profiling, related-substances testing, and forced-degradation studies in pharmaceutical development.
Tizanidine Impurity 46 (C7H4N4S) contains a nitrile group, sulfur-containing functionality, an aromatic ring system. 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).
Recommended for quantitative analysis by HPLC, GC, LC-MS/MS, or GC-MS as an external calibration standard; it can also be used for spiked-recovery experiments, LOD/LOQ determination, and LC-MS/MS multiple-reaction-monitoring (MRM) calibration.
CATO manufactures Tizanidine Impurity 46 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.
