Chemical Structure

Flomoxef Impurity 2 CAS 1208982-59-5 chemical structure

Description

The occurrence of Flomoxef Impurity 2 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 Flomoxef Impurity 2 (CAS 1208982-59-5), a pharmacopoeial impurity reference standard (molecular formula C32H30N6O7S, MW 642.68 g/mol) used for the identification and quantification of trace impurities in APIs.

Based on its molecular formula C32H30N6O7S, Flomoxef Impurity 2 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 642.68 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.

As a certified reference material (CRM), Flomoxef Impurity 2 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.
