46765-03-1 Usage
General Description
4,4'-Sulfonyldiphenol, also known as 4,4'-sulfonyldiphenol or bisphenol S (BPS), is a synthetic organic compound that is used in the production of plastics, epoxy resins, and other industrial materials. It is similar in structure to bisphenol A (BPA) and is often used as a replacement for BPA in various applications. BPS has been found to have endocrine disrupting properties and has been a topic of concern due to its potential for adverse health effects. Research has shown that BPS has the potential to interfere with hormone signaling and may have negative effects on reproductive and developmental processes in animals. Studies also suggest that BPS may have similar health risks to BPA, prompting concerns about its widespread use in consumer products.
Check Digit Verification of cas no
The CAS Registry Mumber 46765-03-1 includes 8 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 5 digits, 4,6,7,6 and 5 respectively; the second part has 2 digits, 0 and 3 respectively.
Calculate Digit Verification of CAS Registry Number 46765-03:
(7*4)+(6*6)+(5*7)+(4*6)+(3*5)+(2*0)+(1*3)=141
141 % 10 = 1
So 46765-03-1 is a valid CAS Registry Number.

Palladium-catalyzed one-step synthesis of symmetrical diaryl sulfones from aryl halides and a sulfur dioxide surrogate
Tanaka, Hiromichi,Konishi, Hideyuki,Manabe, Kei
supporting information, p. 760 - 763 (2019/08/02)
A convenient method for the one-step synthesis of symmetrical diaryl sulfones from aryl halides has been developed. A keystone of the method is the use of K2S2O5, which can be easily and safely handled, as a sulfur dioxide surrogate. The palladium catalyst bearing P(t-Bu)3 as a ligand enables formation of the desired sulfones without significant formation of byproducts.
