rel-​(1R,​2R)​-​1,​2-​Diphenyl-​1,​2-​ethanediol CAS 655-48-1

Description

CATO supplies rel-​(1R,​2R)​-​1,​2-​Diphenyl-​1,​2-​ethanediol (CAS 655-48-1), a certified reference material (molecular formula C14H14O2, MW 214.26 g/mol) for analytical method development and quality control.

Owing to a carboxylic acid group, a hydroxyl group, an ether linkage, a polycyclic aromatic system, rel-​(1R,​2R)​-​1,​2-​Diphenyl-​1,​2-​ethanediol is typically pale yellow to yellow crystalline powder. Its solid-state physicochemical attributes — including a molecular weight of 214.26 g/mol — guide the selection of appropriate sample preparation and analytical techniques. 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.

CATO manufactures rel-​(1R,​2R)​-​1,​2-​Diphenyl-​1,​2-​ethanediol under ISO 17034:2016 accreditation with dual CNAS and ANAB accreditation. Each batch is characterized by orthogonal methods and supplied with a full Certificate of Analysis (COA), ensuring metrological traceability.
