Gadobutrol Impurity 119 CAS CATO-C4X-2120119

Description

Compared with other compounds in its class, the molecular weight of 496.55 g/mol gives Gadobutrol Impurity 119 distinctive chromatographic separation conditions and mass-spectrometry parameter settings.

CATO supplies Gadobutrol Impurity 119 (CAS CATO-C4X-2120119), a pharmacopoeial impurity reference standard (molecular formula C20H40N4O10, MW 496.55 g/mol) used for the identification and quantification of trace impurities in APIs.

Based on its molecular formula C20H40N4O10, Gadobutrol Impurity 119 contains an amide group, a carboxylic acid group, a hydroxyl group, an ether linkage; these features give the compound characteristic absorption bands in UV spectroscopy. The molecular weight of 496.55 g/mol is directly relevant to the identification of the molecular ion in mass spectrometry. 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.

CATO manufactures Gadobutrol Impurity 119 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.
