Chemical Structure

rel-4,4'-((2R,3S)-2,3-Dimethylbutane-1,4-diyl)bis(benzene-1,2-diol) CAS 27686-84-6 chemical structure

Description

CATO manufactures rel-4,4'-((2R,3S)-2,3-Dimethylbutane-1,4-diyl)bis(benzene-1,2-diol) 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.

CATO supplies rel-4,4'-((2R,3S)-2,3-Dimethylbutane-1,4-diyl)bis(benzene-1,2-diol) (CAS 27686-84-6), a certified reference material (molecular formula C18H22O4, MW 302.36 g/mol) for analytical method development and quality control.

The molecular framework of rel-4,4'-((2R,3S)-2,3-Dimethylbutane-1,4-diyl)bis(benzene-1,2-diol) (C18H22O4) is characterized by a flavonoid 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 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.
