Chemical Structure

Cefuroxime Impurity 24 CAS 929531-97-5 chemical structure

Description

The occurrence of Cefuroxime Impurity 24 is closely related to a flavonoid core, 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 Cefuroxime Impurity 24 (CAS 929531-97-5), a pharmacopoeial impurity reference standard (molecular formula C16H16N4O10S, MW 456.38 g/mol) used for the identification and quantification of trace impurities in APIs.

Based on its molecular formula C16H16N4O10S, Cefuroxime Impurity 24 contains a flavonoid core, 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 456.38 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).

Recommended for quantitative analysis by HPLC, GC, LC-MS/MS, or GC-MS as an external calibration standard; it can also be used for spiked-recovery experiments, LOD/LOQ determination, and LC-MS/MS multiple-reaction-monitoring (MRM) calibration.

As a certified reference material (CRM), Cefuroxime Impurity 24 meets the metrological traceability requirements of ISO/IEC 17025 laboratories. Batch-to-batch consistency is monitored via control charts to guarantee comparable assigned values across lots.
