Description

Under current pharmacopoeial and regulatory frameworks, quality-control requirements for this class of reference material explicitly involve the control of targets including 29658-26-2 Methanone, bis(4-fluorophenyl)-, polymer with 1,4-benzenediol 4,4'-Difluorobenzophenone, hydroquinone polymer.

29658-26-2 Methanone, bis(4-fluorophenyl)-, polymer with 1,4-benzenediol 4,4'-Difluorobenzophenone, hydroquinone polymer (CAS 29658-26-2), molecular formula C13H22O3C6H12O2 and molecular weight 342.48 g/mol, is a CATO reference standard with documented purity and traceability.

Structurally, 29658-26-2 Methanone, bis(4-fluorophenyl)-, polymer with 1,4-benzenediol 4,4'-Difluorobenzophenone, hydroquinone polymer (C13H22O3C6H12O2) contains a carboxylic acid group, a hydroxyl group, an ether linkage. The molecule exhibits a degree of unsaturation (DBE) of 3.0, corresponding to approximately 3 ring(s) or double-bond equivalent(s). With a molecular weight of 342.48 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).

This reference standard is suitable for quantitative analysis on major chromatographic platforms including HPLC, GC, LC-MS/MS, and GC-MS, serving as an external calibration standard or a system suitability test reference material.

As a certified reference material (CRM), 29658-26-2 Methanone, bis(4-fluorophenyl)-, polymer with 1,4-benzenediol 4,4'-Difluorobenzophenone, hydroquinone polymer 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.
