[2-(diphenylmethyl)phenyl]methanol is commonly used as a building block in the synthesis of various organic compounds and pharmaceuticals. It can be prepared by the reduction of benzophenone using sodium borohydride or by the Grignard reaction of benzophenone with phenylmagnesium bromide, followed by acidic hydrolysis. [2-(diphenylmethyl)phenyl]methanol is also known by other names such as 1,1'-[2-(diphenylmethyl)phenyl]methanol, benzhydrol, and diphenyl(phenyl)methanol. It has applications in the pharmaceutical, fragrance, and chemical industries.
Check Digit Verification of cas no
The CAS Registry Mumber 6624-01-7 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 4 respectively; the second part has 2 digits, 0 and 1 respectively.
Calculate Digit Verification of CAS Registry Number 6624-01:
(6*6)+(5*6)+(4*2)+(3*4)+(2*0)+(1*1)=87
87 % 10 = 7
So 6624-01-7 is a valid CAS Registry Number.

Electron-transfer-induced reductive cleavage of phthalans: Reactivity and synthetic applications
Azzena, Ugo,Demartis, Salvatore,Melloni, Giovanni
, p. 4913 - 4919 (2007/10/03)
The behavior of phthalan (1a) was investigated under conditions of electron transfer from alkali metals in aprotic solvents. Reaction with lithium in the presence of a catalytic amount of naphthalene in THF led to the reductive cleavage of an arylmethyl carbon-oxygen bond, with formation of a stable dilithium compound. Trapping of this intermediate with several electrophiles (alkyl halides, carbonyl derivatives, CO2) was successful. The extension of this procedure to several substituted phthalans (1b-i) was investigated, and the regiochemistry as well as the synthetic usefulness of these reactions are discussed.
