Rotigotine Impurity 33 CAS CATO-C4X-192733

Description

The occurrence of Rotigotine Impurity 33 is closely related to a nitrogen-containing heterocyclic scaffold, an amide group, a hydroxyl group, an ether linkage in its molecular formula, which determines its behaviour during synthesis, purification, or degradation.

CATO supplies Rotigotine Impurity 33 (CAS CATO-C4X-192733), a pharmacopoeial impurity reference standard (molecular formula C12H17NO, MW 191.27 g/mol) used for the identification and quantification of trace impurities in APIs.

Rotigotine Impurity 33 (C12H17NO) contains a nitrogen-containing heterocyclic scaffold, an amide group, a hydroxyl group, an ether linkage. Its high carbon-to-hydrogen ratio confers good lipid solubility; 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.

CATO manufactures Rotigotine Impurity 33 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.
