1258-75-9 Usage
Uses
Used in Rubber Industry:
2,2'-thiobis(4-nonylphenol) is used as an antioxidant in rubber products to enhance their durability and resistance to degradation, thereby extending their service life and improving performance.
Used in Plastics Industry:
In the plastics industry, 2,2'-thiobis(4-nonylphenol) serves as a stabilizer, preventing the degradation of plastic materials and maintaining their structural integrity over time.
However, due to the growing concern about the environmental and health risks associated with 2,2'-thiobis(4-nonylphenol), regulatory restrictions have been imposed in some regions to limit its use and release into the environment.
Check Digit Verification of cas no
The CAS Registry Mumber 1258-75-9 includes 7 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 4 digits, 1,2,5 and 8 respectively; the second part has 2 digits, 7 and 5 respectively.
Calculate Digit Verification of CAS Registry Number 1258-75:
(6*1)+(5*2)+(4*5)+(3*8)+(2*7)+(1*5)=79
79 % 10 = 9
So 1258-75-9 is a valid CAS Registry Number.

Synthesis and antioxidancy of some n-Alkyl, t-Alkyl, homologous and isomeric lipidic alkylthiobisphenols
Tyman, John H. P.,Johnson, Robert A.
, p. 573 - 578 (2008/09/21)
To study the relationship between structure and properties of members of the lipidic thiobis phenol series, as extreme pressure additives in lubricants, a series of homologous compounds has been synthesised by the reaction of alkylphenols with sulphur dichloride. The isomeric n-nonylphenols have been reacted to form the C9 isomeric 2,2′-and 4,4′-thiobisphenols. Longer alkyl side-chains resulted mainly in the formation of 4,4′-thiobisphenols and some of the 2,2′ isomer. With short alkyl, particularly t-alkyl side-chains, steric hindrance resulted in the 2,2′-compound. Additive studies have indicated that the longer chain 4,4′ compounds possessed antioxidant properties comparable and superior to former commercial branched chain 2,2′ compounds produced from petrochemical intermediates.
