Chemical Structure

Clavulanate Potassium EP Impurity G CAS 374816-32-7 chemical structure

Description

The occurrence of Clavulanate Potassium EP Impurity G is closely related to a nitrogen-containing heterocyclic scaffold, an amide group, a hydroxyl group, an ether linkage in its molecular formula, which determines its behaviour during synthesis, purification, or degradation.

CATO supplies Clavulanate Potassium EP Impurity G (CAS 374816-32-7), a pharmacopoeial impurity reference standard (molecular formula C13H15NO6, MW 281.26 g/mol) used for the identification and quantification of trace impurities in APIs.

Based on its molecular formula C13H15NO6, Clavulanate Potassium EP Impurity G contains a nitrogen-containing heterocyclic scaffold, an amide group, a hydroxyl group, an ether linkage; these features give the compound characteristic absorption bands in UV spectroscopy. The molecular weight of 281.26 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 Clavulanate Potassium EP Impurity G 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.
