693-36-7 Usage
Description
Distearyl thiodipropionate, also known as Dioctadecyl 3,3'-thiodipropionate, is a white powder or particle-form antioxidant commonly used in combination with phenolic antioxidants. It provides excellent long-term thermal stability to materials and is particularly effective in preventing the degradation or oxidative decomposition of organic polymers.
Uses
Used in Plastics and Polymer Industry:
Distearyl thiodipropionate is used as an antioxidant additive for enhancing the stability and longevity of organic polymers. It is particularly effective in reducing the aging properties of poly(1-butene) in hot air aging conditions, thereby improving the overall performance and durability of the material.
Used in Rubber Industry:
In the rubber industry, Distearyl thiodipropionate serves as a vital antioxidant, protecting rubber materials from oxidative degradation and thermal breakdown. This helps maintain the rubber's structural integrity, mechanical properties, and resistance to wear and tear, ensuring a longer service life for rubber products.
Used in Lubricant Industry:
Distearyl thiodipropionate is also utilized as an antioxidant in lubricants to prevent the oxidation of base oils, which can lead to the formation of sludge, varnish, and other deposits. By incorporating Distearyl thiodipropionate into lubricant formulations, the oxidative stability of the lubricant is improved, reducing wear and extending the service life of machinery and equipment.
Used in Cosmetics and Personal Care Industry:
In the cosmetics and personal care industry, Distearyl thiodipropionate is employed as a preservative and antioxidant to protect formulations from oxidative spoilage and degradation. This helps maintain the product's quality, efficacy, and shelf life, ensuring that consumers receive safe and effective products.
Used in Food and Beverage Industry:
Distearyl thiodipropionate is used as an antioxidant in the food and beverage industry to prevent the oxidation of fats and oils, which can lead to rancidity and off-flavors. By incorporating this antioxidant into food products, manufacturers can extend the shelf life of their products and maintain their quality and taste.
Used in Pharmaceutical Industry:
In the pharmaceutical industry, Distearyl thiodipropionate is used as an antioxidant to protect active pharmaceutical ingredients (APIs) from oxidative degradation, ensuring the stability, efficacy, and safety of the final drug product. This is particularly important for drugs that are sensitive to oxidation and require protection to maintain their therapeutic properties.

Check Digit Verification of cas no
The CAS Registry Mumber 693-36-7 includes 6 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 3 digits, 6,9 and 3 respectively; the second part has 2 digits, 3 and 6 respectively.
Calculate Digit Verification of CAS Registry Number 693-36:
(5*6)+(4*9)+(3*3)+(2*3)+(1*6)=87
87 % 10 = 7
So 693-36-7 is a valid CAS Registry Number.

Esters of Thiodiglycollic and Thiodipropionic Acids and 2,5-Dicarboxy-3,4-dihydroxythiophene as Potential Slow Acting Anticancer Agents
Kumar, Anil,Tilak, B. D.
, p. 880 - 882 (2007/10/02)
A series of esters of thiodiglycollic and thiodipropionic acids and 2,5-dicarboxy-3,4-dihydroxythiophene have been synthesised with a view to testing their anticancer properties.The esters, as against parent acids are expected to have a prolonged effect.
