Latamoxef Impurity 1 CAS 75007-70-4

Description

The occurrence of Latamoxef Impurity 1 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 Latamoxef Impurity 1 (CAS 75007-70-4), a pharmacopoeial impurity reference standard (molecular formula C19H20N6O7S, MW 476.46 g/mol) used for the identification and quantification of trace impurities in APIs.

Owing to a flavonoid core, an amide group, a sulfone group, a hydroxyl group, an ether linkage, Latamoxef Impurity 1 is typically pale yellow to yellow crystalline powder. Its solid-state physicochemical attributes — including a molecular weight of 476.46 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), Latamoxef Impurity 1 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.
