693-36-7 Usage

Description

Antioxidant DSTP is usually in the form of white particles or powder, which can impart excellent long-term thermal stability to the material, and is usually used in combination with phenolic antioxidants.

Uses

Dioctadecyl 3,3’-Thiodipropionate (CAS# 693-36-7) is an antioxidant additive added to prevent degredation or oxidative decomposition of the organic polymers. Dioctadecyl 3,3’-Thiodipropionate has decreased the aging properties of poly(1-butene) in a hot air aging box.

Flammability and Explosibility

Notclassified

Safety Profile

When heated to decomposition emits toxic fumes of SOx,

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.
