Bis-<1-aethyl-cyclohexyl>-oxalat, also known as bis(1-ethylcyclohexyl) oxalate, is an organic compound with the chemical formula C16H26O4. It is a white crystalline solid that is soluble in organic solvents. Bis-<1-aethyl-cyclohexyl>-oxalat is primarily used as a plasticizer, which is a substance added to plastics to increase their flexibility, workability, or durability. Bis(1-ethylcyclohexyl) oxalate is particularly effective in enhancing the properties of polyvinyl chloride (PVC) and other polymers. It is valued for its low volatility, high boiling point, and resistance to extraction by water, which contribute to its stability and performance in various applications.
The CAS Registry Mumber 739-18-4 includes 6 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 3 digits, 7,3 and 9 respectively; the second part has 2 digits, 1 and 8 respectively. Calculate Digit Verification of CAS Registry Number 739-18: (5*7)+(4*3)+(3*9)+(2*1)+(1*8)=84 84 % 10 = 4 So 739-18-4 is a valid CAS Registry Number.
