Phenol, 4,4'-(3-methylbutylidene)bis-, also known as bisphenol A (BPA), is an organic compound with the chemical formula C15H16O2. It is a white crystalline solid that is soluble in organic solvents and has a melting point of 158-159°C. BPA is primarily used in the production of polycarbonate plastics and epoxy resins, which are commonly found in various consumer products such as food containers, water bottles, and dental sealants. Due to its widespread use and potential health concerns, BPA has been the subject of extensive research and debate, with some countries implementing restrictions on its use in certain applications.

2081-32-5 Usage

Check Digit Verification of cas no

The CAS Registry Mumber 2081-32-5 includes 7 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 4 digits, 2,0,8 and 1 respectively; the second part has 2 digits, 3 and 2 respectively.
Calculate Digit Verification of CAS Registry Number 2081-32:
(6*2)+(5*0)+(4*8)+(3*1)+(2*3)+(1*2)=55
55 % 10 = 5
So 2081-32-5 is a valid CAS Registry Number.

Linear free-energy relationship analysis of a catalytic desymmetrization reaction of a diarylmethane-bis(phenol)

Gustafson, Jeffrey L.,Sigman, Matthew S.,Miller, Scott J.

supporting information; experimental part, p. 2794 - 2797 (2010/09/04)

(Figure presented) Linear free-energy relationships have been found for enantioselectivity and various steric parameters in an enantioselective desymmetrization of symmetrical bis(phenol) substrates. The potential origin of this observation and the role of different steric parameters are discussed.
