(1''S)-4',5',5'',6''-Tetramethyl-[1,1':3',1'':3'',1'''-quaterphenyl]-2',2''-diol CAS 619323-98-7

Description

The occurrence of (1''S)-4',5',5'',6''-Tetramethyl-[1,1':3',1'':3'',1'''-quaterphenyl]-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.

CATO supplies (1''S)-4',5',5'',6''-Tetramethyl-[1,1':3',1'':3'',1'''-quaterphenyl]-2',2''-diol (CAS 619323-98-7), a certified reference material (molecular formula C28H26O2, MW 394.50 g/mol) for analytical method development and quality control.

Owing to a steroid core, a hydroxyl group, an ether linkage, (1''S)-4',5',5'',6''-Tetramethyl-[1,1':3',1'':3'',1'''-quaterphenyl]-2',2''-diol is typically pale yellow to yellow crystalline powder. Its solid-state physicochemical attributes — including a molecular weight of 394.50 g/mol — guide the selection of appropriate sample preparation and analytical techniques. 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.

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.
