Chemical Structure

Rotigotine Impurity 36 CAS CATO-C4X-192736 chemical structure

Description

The assigned purity is verified by mass-balance and quantitative NMR (qNMR) approaches, with the expanded uncertainty reported at a 95% confidence level (k=2). Batch homogeneity and stability are independently assessed for every lot.

Rotigotine Impurity 36 (CAS CATO-C4X-192736) is a certified pharmaceutical impurity reference standard with the molecular formula C17H21NOSC2H3O3 and a molecular weight of 362.46 g/mol.

Rotigotine Impurity 36 (C17H21NOSC2H3O3) 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. Nitrogen-containing functional groups confer excellent ionization efficiency in positive-ion electrospray (ESI) mode, making the compound well suited to LC-MS/MS analysis.

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.
