Chemical Structure

Nemonoxacin Impurity 54 CAS 269407-02-5 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 Nemonoxacin Impurity 54.

As a process- or degradation-related impurity, Nemonoxacin Impurity 54 (CAS 269407-02-5, C14H12FNO4) is essential for impurity profiling, related-substances testing, and forced-degradation studies in pharmaceutical development.

Owing to a nitrogen-containing heterocyclic scaffold, an amide group, a hydroxyl group, an ether linkage, fluorine substitution, Nemonoxacin Impurity 54 is typically pale yellow to yellow crystalline powder. Its solid-state physicochemical attributes — including a molecular weight of 277.25 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), Nemonoxacin Impurity 54 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.
