Firstly, 2,4-dimethyl-6-tert-butylphenol is reacted with formaldehyde and HCl (Blanc reaction) to generate a chloromethyl group in the less hindered meta position. This intermediate then reacts with cyanuric acid to give the desired product.
Tris(3,5-di-tert-butyl-4-hydroxybenzyl) isocyanurate is a chemical compound used as a polymer stabilizer in plastics. Like other hindered phenols it acts as a primary antioxidant. More than 1000 tonnes per year are used in the EU.
Pentaerythritol tetrakis(3,5-di-tert-butyl-4-hydroxyhydrocinnamate) is a chemical compound composed of four sterically hindered phenols linked through a pentaerythritol core. It is used as primary antioxidant for stabilizing polymers, particularly polyethylene and polypropylene.
Probucol, sold under the trade name Lorelco among others, is an anti-hyperlipidemic drug [1] initially developed for the treatment of coronary artery disease.Clinical use was discontinued in some countries after it was found that the drug may have the undesired effect of lowering HDL in patients with a previous history of heart disease.

4-tert-Butylphenol is an organic compound with the formula (CH 3) 3 CC 6 H 4 OH. It is one of three isomeric tert-butyl phenols. It is a white solid with a distinct phenolic odor. It dissolves in basic water. [2]
The chemical synthesis of BHT in industry has involved the reaction of p-cresol (4-methylphenol) with isobutylene (2-methylpropene), catalyzed by sulfuric acid: [11] CH 3 (C 6 H 4)OH + 2 CH 2 =C(CH 3) 2 → ((CH 3) 3 C) 2 CH 3 C 6 H 2 OH. Alternatively, BHT has been prepared from 2,6-di-tert-butylphenol by hydroxymethylation or aminomethylation ...
