Chemical Structure

3,3',5,5'-Tetra-tert-butyl-2,2'-dihydroxybiphenyl CAS 6390-69-8 chemical structure

Description

Compared with other compounds in its class, the molecular weight of 410.63 g/mol gives 3,3',5,5'-Tetra-tert-butyl-2,2'-dihydroxybiphenyl distinctive chromatographic separation conditions and mass-spectrometry parameter settings.

3,3',5,5'-Tetra-tert-butyl-2,2'-dihydroxybiphenyl (CAS 6390-69-8), molecular formula C28H42O2 and molecular weight 410.63 g/mol, is a CATO reference standard with documented purity and traceability.

Owing to a steroid core, a hydroxyl group, an ether linkage, 3,3',5,5'-Tetra-tert-butyl-2,2'-dihydroxybiphenyl is typically pale yellow to yellow crystalline powder. Its solid-state physicochemical attributes — including a molecular weight of 410.63 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.
