Benzene-1,2-diylbis[(4-methoxyphenyl)methanol], also known as bisphenol S, is an organic compound with the chemical formula C20H20O4. It is a white crystalline solid that is soluble in organic solvents and has a molecular weight of 328.37 g/mol. Bisphenol S is a synthetic compound that is structurally similar to bisphenol A (BPA), but with two methoxy groups attached to the phenyl rings. It is primarily used as a monomer in the production of various polymers, including epoxy resins and polycarbonate plastics. These materials are widely used in food packaging, water bottles, and other consumer products. Bisphenol S has been a subject of research due to potential health concerns, as it has been found to exhibit estrogenic activity and may have endocrine-disrupting effects. As a result, there has been a growing interest in finding safer alternatives to bisphenol S in consumer products.

6636-09-5 Usage

Check Digit Verification of cas no

The CAS Registry Mumber 6636-09-5 includes 7 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 4 digits, 6,6,3 and 6 respectively; the second part has 2 digits, 0 and 9 respectively.
Calculate Digit Verification of CAS Registry Number 6636-09:
(6*6)+(5*6)+(4*3)+(3*6)+(2*0)+(1*9)=105
105 % 10 = 5
So 6636-09-5 is a valid CAS Registry Number.

Improved synthesis of aryl-substituted anthracenes and heteroacenes

Li, Guijie,Zhou, Shaolin,Su, Guowei,Liu, Yuanhong,Wang, Peng George

, p. 9830 - 9833 (2008/03/28)

(Chemical Equation Presented) A Bronsted acid-catalyzed highly efficient construction of substituted arylanthracenes and heteroacenes is described, which is assumed to be initiated through the facile formation of a benzylic cation intermediate. This method offers several advantages in comparison with known aromatic cyclodehydration reactions such as high selectivities, mild reaction conditions, and easily accessible starting materials.
