Chemical Structure

Benzbromarone Impurity 31 CAS CATO-C4X-225031 chemical structure

Description

The occurrence of Benzbromarone Impurity 31 is closely related to a steroid core, a hydroxyl group, an ether linkage in its molecular formula, which determines its behaviour during synthesis, purification, or degradation.

As a process- or degradation-related impurity, Benzbromarone Impurity 31 (CAS CATO-C4X-225031, C26H22O5) is essential for impurity profiling, related-substances testing, and forced-degradation studies in pharmaceutical development.

Structurally, Benzbromarone Impurity 31 (C26H22O5) contains a steroid core, a hydroxyl group, an ether linkage. The molecule exhibits a degree of unsaturation (DBE) of 16.0, corresponding to approximately 16 ring(s) or double-bond equivalent(s). With a molecular weight of 414.45 g/mol, it falls into the moderately-high-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).

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), Benzbromarone Impurity 31 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.
