Chemical Structure

3,3',5,5',6,6'-Hexamethyl-[1,1'-biphenyl]-2,2'-diol CAS 110932-47-3 chemical structure

Description

The occurrence of 3,3',5,5',6,6'-Hexamethyl-[1,1'-biphenyl]-2,2'-diol is closely related to a steroid core, a hydroxyl group, an ether linkage in its molecular formula, which determines its behaviour during synthesis, purification, or degradation.

3,3',5,5',6,6'-Hexamethyl-[1,1'-biphenyl]-2,2'-diol (CAS 110932-47-3) is a high-purity analytical reference standard with the molecular formula C18H22O2 and a molecular weight of 270.37 g/mol.

The molecular framework of 3,3',5,5',6,6'-Hexamethyl-[1,1'-biphenyl]-2,2'-diol (C18H22O2) 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.

The assigned purity is verified by mass-balance and quantitative NMR (qNMR) approaches, with the expanded uncertainty reported at a 95% confidence level (k=2). Batch homogeneity and stability are independently assessed for every lot.
