Chemical Structure

4-(Hydroxydiphenylmethyl)phenol CAS 15658-11-4 chemical structure

Description

The molecular framework of 4-(Hydroxydiphenylmethyl)phenol (C19H16O2) 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).

4-(Hydroxydiphenylmethyl)phenol (CAS 15658-11-4), molecular formula C19H16O2 and molecular weight 276.33 g/mol, is a CATO reference standard with documented purity and traceability.

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), 4-(Hydroxydiphenylmethyl)phenol 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.
