3,3’,5,5’-TETRA-T-BUTYLBIPHENYL-2,2’,6,6’-TETRAOL CAS 21243-76-5

Description

The occurrence of 3,3’,5,5’-TETRA-T-BUTYLBIPHENYL-2,2’,6,6’-TETRAOL 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 3,3’,5,5’-TETRA-T-BUTYLBIPHENYL-2,2’,6,6’-TETRAOL (CAS 21243-76-5), a certified reference material (molecular formula C28H42O4, MW 442.63 g/mol) for analytical method development and quality control.

Owing to a steroid core, a hydroxyl group, an ether linkage, 3,3’,5,5’-TETRA-T-BUTYLBIPHENYL-2,2’,6,6’-TETRAOL is typically pale yellow to yellow crystalline powder. Its solid-state physicochemical attributes — including a molecular weight of 442.63 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).

Recommended for analytical method development and validation; each product is supplied with a full Certificate of Analysis (COA) ensuring ISO 17034 metrological traceability.

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.
