1-(2-Hydroxyphenyl)-2-phenylethan-1-one CAS 2491-31-8 chemical structure

Description

Compared with other compounds in its class, the molecular weight of 212.24 g/mol gives 1-(2-Hydroxyphenyl)-2-phenylethan-1-one distinctive chromatographic separation conditions and mass-spectrometry parameter settings.

CATO supplies 1-(2-Hydroxyphenyl)-2-phenylethan-1-one (CAS 2491-31-8), a certified reference material (molecular formula C14H12O2, MW 212.24 g/mol) for analytical method development and quality control.

Structurally, 1-(2-Hydroxyphenyl)-2-phenylethan-1-one (C14H12O2) contains a carboxylic acid group, a hydroxyl group, an ether linkage, a polycyclic aromatic system. The molecule exhibits a degree of unsaturation (DBE) of 9.0, corresponding to approximately 9 ring(s) or double-bond equivalent(s). With a molecular weight of 212.24 g/mol, it falls into the medium-molecular-weight range. The high carbon-to-hydrogen ratio imparts good lipophilicity, allowing liquid-liquid extraction with non-polar solvents such as n-hexane or ethyl acetate.

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), 1-(2-Hydroxyphenyl)-2-phenylethan-1-one 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.
