Chemical Structure

Fluconazole Impurity 23 CAS 1609495-95-5 chemical structure

Description

The occurrence of Fluconazole Impurity 23 is closely related to a nitrogen-containing heterocyclic scaffold, an amide group, a hydroxyl group, an ether linkage, fluorine substitution in its molecular formula, which determines its behaviour during synthesis, purification, or degradation.

CATO supplies Fluconazole Impurity 23 (CAS 1609495-95-5), a pharmacopoeial impurity reference standard (molecular formula C15H14FN9O, MW 355.33 g/mol) used for the identification and quantification of trace impurities in APIs.

Fluconazole Impurity 23 (C15H14FN9O) contains a nitrogen-containing heterocyclic scaffold, an amide group, a hydroxyl group, an ether linkage, fluorine substitution. Halogen substitution raises its density and boiling point; these physicochemical properties determine the optimal preparation and storage of its standard solutions. 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.

The assigned purity is verified by mass-balance and quantitative NMR (qNMR) approaches, with the expanded uncertainty reported at a 95% confidence level (k=2). Batch homogeneity and stability are independently assessed for every lot.
