4275-31-4

Didodecanoic acid thiobis(2,1-ethanediyl) ester, also known as bis(2-ethylhexyl) thiophosphate or DEHP, is a colorless, odorless, and oily liquid chemical compound with the molecular formula C24H46O4P. It is primarily used as a plasticizer to increase the flexibility, durability, and longevity of various materials, such as PVC plastics, adhesives, and coatings. DEHP is also employed in the production of medical devices, such as blood bags and tubing, due to its ability to enhance the flexibility and durability of these products. However, concerns have been raised regarding its potential health and environmental impacts, as it can leach out of products and accumulate in the environment, posing risks to human health and wildlife. As a result, there has been a growing interest in finding alternative plasticizers with lower toxicity and environmental persistence.

4275-31-4 Usage

Check Digit Verification of cas no

The CAS Registry Mumber 4275-31-4 includes 7 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 4 digits, 4,2,7 and 5 respectively; the second part has 2 digits, 3 and 1 respectively.
Calculate Digit Verification of CAS Registry Number 4275-31:
(6*4)+(5*2)+(4*7)+(3*5)+(2*3)+(1*1)=84
84 % 10 = 4
So 4275-31-4 is a valid CAS Registry Number.

Selective synthesis of thiodiglycol dicarboxylic acid esters via p-TsOH/C-catalysed direct esterification

Jiang, Dahong,Huang, Min

, p. 1087 - 1090 (2013/03/28)

The esterification of thiodiglycol and long alkyl-chain carboxylic acids is reported. Reaction of thiodiglycol with carboxylic acid via p-TsOH/C-catalysed direct esterification afforded thiodiglycol dicarboxylic acid esters in good yields and chemoselectivity. The use of immobilized p-TsOH on activated carbon as catalyst is crucial for the transformation. Indian Academy of Sciences.
