(4-Ethenylphenyl)diphenyl methanol, also known as 1-(4-vinylphenyl)-1,1-diphenylmethanol or 4-allyl-α,α-diphenylbenzyl alcohol, is an organic compound with the chemical formula C18H18O. It is a colorless to pale yellow liquid with a molecular weight of 250.33 g/mol. (4-ethenylphenyl)diphenyl methanol is characterized by a phenyl group (C6H5) attached to a vinyl group (C2H3) at the para position, and two additional phenyl groups attached to a central methanol group (CH2OH). It is used as an intermediate in the synthesis of various pharmaceuticals, agrochemicals, and other specialty chemicals. Due to its complex structure and reactivity, it is typically handled by professionals in controlled environments.

3139-86-4 Usage

Check Digit Verification of cas no

The CAS Registry Mumber 3139-86-4 includes 7 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 4 digits, 3,1,3 and 9 respectively; the second part has 2 digits, 8 and 6 respectively.
Calculate Digit Verification of CAS Registry Number 3139-86:
(6*3)+(5*1)+(4*3)+(3*9)+(2*8)+(1*6)=84
84 % 10 = 4
So 3139-86-4 is a valid CAS Registry Number.

An improved and general synthesis of monomers for incorporating trityl linker groups into polystyrene synthesis supports

Choi, Matthew Kwok Wai,Toy, Patrick H.

, p. 2903 - 2907 (2007/10/03)

A straightforward synthesis of trityl alcohols in which one of the aryl rings is substituted with a vinyl group is presented. The synthesis of the alcohols involves the direct addition of the Grignard reagent prepared from 4-bromostyrene to substituted be

Improved synthesis of (4-ethenylphenyl)diphenyl methanol and its application in the preparation of trityl functionalized polystyrene resin containing tetrahydrofuran derived cross-linker

Manzotti,Reger,Janda

, p. 8417 - 8420 (2007/10/03)

An improved and straightforward synthesis of (4-ethenylphenyl)diphenyl methanol is described. This monomer was used in the preparation of trityl functionalized polystyrene containing a flexible tetrahydrofuran cross-linker, giving rise to a suitable support for solid-phase organic synthesis.
