Chemical Structure

Fluralaner Impurity 4 (mix TBC as stabilizer) CAS 864725-22-4 chemical structure

Description

Structurally, Fluralaner Impurity 4 (mix TBC as stabilizer) (C9H5Cl2F3) contains fluorine/chlorine substitution, an aromatic ring system. The molecule exhibits a degree of unsaturation (DBE) of 5.0, corresponding to approximately 5 ring(s) or double-bond equivalent(s). With a molecular weight of 241.04 g/mol, it falls into the medium-molecular-weight range. 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).

CATO supplies Fluralaner Impurity 4 (mix TBC as stabilizer) (CAS 864725-22-4), a pharmacopoeial impurity reference standard (molecular formula C9H5Cl2F3, MW 241.04 g/mol) used for the identification and quantification of trace impurities in APIs.

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), Fluralaner Impurity 4 (mix TBC as stabilizer) 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.
