1258-75-9 Usage
General Description
2,2'-thiobis(4-nonylphenol) is a chemical compound that is often used as an antioxidant in rubber products and as a stabilizer in plastics. It is a member of the family of nonylphenol compounds, which are known for their endocrine-disrupting properties and potential harmful effects on the environment. Due to its chemical structure, 2,2'-thiobis(4-nonylphenol) is persistent in the environment and has been found in soil, water, and biota. Studies have shown that it can negatively impact aquatic organisms and may have toxic effects on human health. As a result, there is growing concern about the use and release of 2,2'-thiobis(4-nonylphenol) into the environment, leading to regulatory restrictions in some regions.
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.
