Chemical Structure
Description
Compared with other compounds in its class, the molecular weight of 565.63 g/mol gives Thiocolchicoside EP Impurity L distinctive chromatographic separation conditions and mass-spectrometry parameter settings.
CATO supplies Thiocolchicoside EP Impurity L (CAS CATO-C4X-27707), a pharmacopoeial impurity reference standard (molecular formula C27H35NO10S, MW 565.63 g/mol) used for the identification and quantification of trace impurities in APIs.
The molecular framework of Thiocolchicoside EP Impurity L (C27H35NO10S) is characterized by a nitrogen-containing heterocyclic scaffold, an amide group, a sulfone group, a hydroxyl group, an ether linkage. In reversed-phase chromatography, its retention is governed primarily by the protonation state of its nitrogen-containing groups, which provides a practical basis for HPLC-UV/DAD or LC-MS method development. 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 Thiocolchicoside EP Impurity L 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.
