Flurbiprofen Impurity 83 CAS CATO-C4X-144483

Description

The occurrence of Flurbiprofen Impurity 83 is closely related to a carboxylic acid group, a hydroxyl group, an ether linkage, fluorine substitution, a polycyclic aromatic system in its molecular formula, which determines its behaviour during synthesis, purification, or degradation.

As a process- or degradation-related impurity, Flurbiprofen Impurity 83 (CAS CATO-C4X-144483, C28H32F2O8) is essential for impurity profiling, related-substances testing, and forced-degradation studies in pharmaceutical development.

Owing to a carboxylic acid group, a hydroxyl group, an ether linkage, fluorine substitution, a polycyclic aromatic system, Flurbiprofen Impurity 83 is typically pale yellow to yellow crystalline powder. Its solid-state physicochemical attributes — including a molecular weight of 534.55 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).

Recommended for quantitative analysis by HPLC, GC, LC-MS/MS, or GC-MS as an external calibration standard; it can also be used for spiked-recovery experiments, LOD/LOQ determination, and LC-MS/MS multiple-reaction-monitoring (MRM) calibration.

As a certified reference material (CRM), Flurbiprofen Impurity 83 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.
