Aluminum, tri-2-propenyl-, also known as triallylaluminum or TAA, is an organoaluminum compound with the chemical formula (C3H5)3Al. It is a colorless, highly reactive, and pyrophoric liquid, which means it ignites spontaneously upon contact with air. TAA is widely used as a cocatalyst in the production of polyolefins, particularly in the Ziegler-Natta polymerization process, where it helps to control the molecular weight and stereochemistry of the resulting polymers. Due to its high reactivity, TAA must be handled with extreme caution, typically under an inert atmosphere or in a sealed system to prevent unwanted reactions.

18854-66-5 Usage
Check Digit Verification of cas no
The CAS Registry Mumber 18854-66-5 includes 8 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 5 digits, 1,8,8,5 and 4 respectively; the second part has 2 digits, 6 and 6 respectively.Calculate Digit Verification of CAS Registry Number 18854-66:
(7*1)+(6*8)+(5*8)+(4*5)+(3*4)+(2*6)+(1*6)=145
145 % 10 = 5
So 18854-66-5 is a valid CAS Registry Number.
