Chemical Structure

Ceftazidime Impurity 101 CAS CATO-C4X-1212101 chemical structure

Description

The occurrence of Ceftazidime Impurity 101 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 Ceftazidime Impurity 101 (CAS CATO-C4X-1212101), a pharmacopoeial impurity reference standard (molecular formula C31H37N7O12S3, MW 795.86 g/mol) used for the identification and quantification of trace impurities in APIs.

Structurally, Ceftazidime Impurity 101 (C31H37N7O12S3) contains a nitrogen-containing heterocyclic scaffold, an amide group, a sulfone group, a hydroxyl group, an ether linkage. The molecule exhibits a degree of unsaturation (DBE) of 17.0, corresponding to approximately 17 ring(s) or double-bond equivalent(s). With a molecular weight of 795.86 g/mol, it falls into the high-molecular-weight range. 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 Ceftazidime Impurity 101 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.
