Chemical Structure

Thiocolchicoside EP Impurity J (Thiocolchicoside Impurity D1SO) (Mixture of Diastereomers) CAS 1359973-79-7 chemical structure

Description

The molecular framework of Thiocolchicoside EP Impurity J (Thiocolchicoside Impurity D1SO) (Mixture of Diastereomers) (C27H33NO11S) 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).

As a process- or degradation-related impurity, Thiocolchicoside EP Impurity J (Thiocolchicoside Impurity D1SO) (Mixture of Diastereomers) (CAS 1359973-79-7, C27H33NO11S) is essential for impurity profiling, related-substances testing, and forced-degradation studies in pharmaceutical development.

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 J (Thiocolchicoside Impurity D1SO) (Mixture of Diastereomers) 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.
