Propanedioic acid, dioctyl-, also known as dioctyl adipate or DOA, is a colorless to pale yellow liquid with the chemical formula C24H46O4. It is an organic compound derived from the esterification of propylene glycol and octanoic acid, and is commonly used as a plasticizer in the production of various polymers, such as PVC, cellulose acetate, and polystyrene. DOA is known for its excellent low-temperature flexibility, resistance to extraction, and compatibility with a wide range of polymers. It is widely used in the manufacturing of adhesives, sealants, coatings, and elastomers, as well as in the production of lubricants and fuel additives. However, it is important to note that DOA is considered a potential health hazard and should be handled with care due to its potential to cause skin and eye irritation, as well as its classification as a reproductive toxin.
The CAS Registry Mumber 4372-37-6 includes 7 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 4 digits, 4,3,7 and 2 respectively; the second part has 2 digits, 3 and 7 respectively. Calculate Digit Verification of CAS Registry Number 4372-37: (6*4)+(5*3)+(4*7)+(3*2)+(2*3)+(1*7)=86 86 % 10 = 6 So 4372-37-6 is a valid CAS Registry Number.
