Chemical Structure

Rotigotine Impurity 38 CAS CATO-C4X-192738 chemical structure

Description

The occurrence of Rotigotine Impurity 38 is closely related to a flavonoid core, an amide group, a sulfone group, a hydroxyl group, an ether linkage in its molecular formula, which determines its behaviour during synthesis, purification, or degradation.

CATO supplies Rotigotine Impurity 38 (CAS CATO-C4X-192738), a pharmacopoeial impurity reference standard (molecular formula C17H21NOS*C2H3O3, MW 362.42 g/mol) used for the identification and quantification of trace impurities in APIs.

Rotigotine Impurity 38 (C17H21NOS*C2H3O3) contains a flavonoid core, an amide group, a sulfone group, a hydroxyl group, an ether linkage. 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).

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 Rotigotine Impurity 38 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.
