7597-97-9 Usage
General Description
2-tert-butyl-4-isopropylphenol, also known as butylated hydroxytoluene (BHT), is an aromatic organic compound with the chemical formula C15H24O. It is a type of phenol compound that is often used as an antioxidant in various products such as food, cosmetics, and pharmaceuticals to prevent them from spoiling or becoming rancid. BHT is synthesized by the alkylation of phenol with isobutylene and isopropyl alcohol. It is a white, crystalline solid that is insoluble in water, but soluble in organic solvents such as ethanol and acetone. BHT is considered safe for use in small amounts, but excessive consumption may have adverse health effects.
Check Digit Verification of cas no
The CAS Registry Mumber 7597-97-9 includes 7 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 4 digits, 7,5,9 and 7 respectively; the second part has 2 digits, 9 and 7 respectively.
Calculate Digit Verification of CAS Registry Number 7597-97:
(6*7)+(5*5)+(4*9)+(3*7)+(2*9)+(1*7)=149
149 % 10 = 9
So 7597-97-9 is a valid CAS Registry Number.

Controlling the catalytic aerobic oxidation of phenols

The oxidation of phenols is the subject of extensive investigation, but there are few catalytic aerobic examples that are chemo- and regioselective. Here we describe conditions for the ortho-oxygenation or oxidative coupling of phenols under copper (Cu)-catalyzed aerobic conditions that give rise to ortho-quinones, biphenols or benzoxepines. We demonstrate that each product class can be accessed selectively by the appropriate choice of Cu(I) salt, amine ligand, desiccant and reaction temperature. In addition, we evaluate the effects of substituents on the phenol and demonstrate their influence on selectivity between ortho-oxygenation and oxidative coupling pathways. These results create an important precedent of catalyst control in the catalytic aerobic oxidation of phenols and set the stage for future development of catalytic systems and mechanistic investigations.
