Rotigotine Impurity 41 CAS CATO-C4X-192741

Description

Under current pharmacopoeial and regulatory frameworks, quality-control requirements for this class of reference material explicitly involve the control of targets including Rotigotine Impurity 41.

CATO supplies Rotigotine Impurity 41 (CAS CATO-C4X-192741), a pharmacopoeial impurity reference standard (molecular formula C11H10O2, MW 174.20 g/mol) used for the identification and quantification of trace impurities in APIs.

Based on its molecular formula C11H10O2, Rotigotine Impurity 41 contains a carboxylic acid group, a hydroxyl group, an ether linkage, an aromatic ring system; these features give the compound characteristic absorption bands in UV spectroscopy. The molecular weight of 174.20 g/mol is directly relevant to the identification of the molecular ion in mass spectrometry. The high carbon-to-hydrogen ratio imparts good lipophilicity, allowing liquid-liquid extraction with non-polar solvents such as n-hexane or ethyl acetate.

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 41 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.
