Sulbenicillin Impurity 3 CAS CATO-C4X-23243

Description

The occurrence of Sulbenicillin Impurity 3 is closely related to a nitrogen-containing heterocyclic scaffold, 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 Sulbenicillin Impurity 3 (CAS CATO-C4X-23243), a pharmacopoeial impurity reference standard (molecular formula C10H11NO6S, MW 273.26 g/mol) used for the identification and quantification of trace impurities in APIs.

Based on its molecular formula C10H11NO6S, Sulbenicillin Impurity 3 contains a nitrogen-containing heterocyclic scaffold, an amide group, a sulfone group, a hydroxyl group, an ether linkage; these features give the compound characteristic absorption bands in UV spectroscopy. The molecular weight of 273.26 g/mol is directly relevant to the identification of the molecular ion in mass spectrometry. 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 Sulbenicillin Impurity 3 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.
