Chemical Structure

Flomoxef Impurity 7 CAS 2095697-76-8 chemical structure

Description

Under current pharmacopoeial and regulatory frameworks, quality-control requirements for this class of reference material explicitly involve the control of targets including Flomoxef Impurity 7.

CATO supplies Flomoxef Impurity 7 (CAS 2095697-76-8), a pharmacopoeial impurity reference standard (molecular formula C12H14F2N2O7S, MW 368.31 g/mol) used for the identification and quantification of trace impurities in APIs.

Owing to a nitrogen-containing heterocyclic scaffold, an amide group, a sulfone group, a hydroxyl group, an ether linkage, fluorine substitution, Flomoxef Impurity 7 is typically off-white to pale yellow crystalline powder. Its solid-state physicochemical attributes — including a molecular weight of 368.31 g/mol — guide the selection of appropriate sample preparation and analytical techniques. The presence of an aromatic ring or conjugated system gives the compound characteristic absorption bands in the UV-Vis region, making it well suited to UV or diode-array detection (DAD).

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 7 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.
