6627-39-0 Usage
General Description
2,6-dibenzyl-4-methylphenol, also known as BHT, is a chemical compound with antioxidant properties and is commonly used as a food preservative. It is a white, crystalline substance that is soluble in organic solvents and insoluble in water. BHT is used in a variety of products, including cosmetics, pharmaceuticals, and industrial applications, to prevent oxidation and extend shelf life. Studies have shown that BHT may have potential health risks, including potential carcinogenic effects, and there have been concerns about its safety and use in food products. Despite this, BHT continues to be widely used as a preservative in various consumer products.
Check Digit Verification of cas no
The CAS Registry Mumber 6627-39-0 includes 7 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 4 digits, 6,6,2 and 7 respectively; the second part has 2 digits, 3 and 9 respectively.
Calculate Digit Verification of CAS Registry Number 6627-39:
(6*6)+(5*6)+(4*2)+(3*7)+(2*3)+(1*9)=110
110 % 10 = 0
So 6627-39-0 is a valid CAS Registry Number.

Towards ortho-selective electrophilic substitution/addition to phenolates in anhydrous solvents
Lopu?anskaja, Eleana,Kooli, Anni,Paju, Anne,J?rving, Ivar,Lopp, Margus
, (2021/02/16)
Alkyl-substituted Li-phenolates with BnBr in water solution lead to a mixture of o- and p-Bn-substituted phenols together with a substantial amount of phenol Bn ether. In CPME, and especially in toluene with 1–2 equivalents of ether or alcohol additives, ortho-selective alkylation is achieved. In the case of o,o,p-tri- and o,o-di-substituted phenols dearomatization occurs affording o-Bn-substituted alkyl cyclohexadienones with yields up to 92% with an o/p ratio up to 90/1.
