Chemical Structure

4-(Diphenylmethylene)cyclohexa-2,5-dienone CAS 479-71-0 chemical structure

Description

As a certified reference material (CRM), 4-(Diphenylmethylene)cyclohexa-2,5-dienone 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.

4-(Diphenylmethylene)cyclohexa-2,5-dienone (CAS 479-71-0) is a high-purity analytical reference standard with the molecular formula C19H14O and a molecular weight of 258.31 g/mol.

The molecular framework of 4-(Diphenylmethylene)cyclohexa-2,5-dienone (C19H14O) is characterized by a steroid core, a hydroxyl group, an ether linkage. In reversed-phase chromatography, its retention is governed primarily by its high hydrophobicity (logP), which provides a practical basis for HPLC-UV/DAD or LC-MS method development. The aromatic system may exhibit native fluorescence, enabling detection with a fluorescence detector (FLD).

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.
