4-Methyl-2-(tributyl-stannyloxy)-pent-2-en is an organotin compound characterized by a pent-2-en backbone with a methyl group at the 4th position and a tributylstannyl group attached to the oxygen atom at the 2nd position. 4-Methyl-2--pent-2-en is a colorless liquid with a molecular formula of C19H40OSn and a molecular weight of 393.22 g/mol. It is primarily used as a reagent in organic synthesis, particularly in the formation of carbon-carbon bonds through the Stille coupling reaction, a type of cross-coupling reaction. The tributylstannyl group acts as a nucleophile, facilitating the coupling process. Due to its reactivity and potential toxicity, it is important to handle 4-Methyl-2--pent-2-en with care, following appropriate safety protocols.

681-95-8 Usage
Check Digit Verification of cas no
The CAS Registry Mumber 681-95-8 includes 6 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 3 digits, 6,8 and 1 respectively; the second part has 2 digits, 9 and 5 respectively.Calculate Digit Verification of CAS Registry Number 681-95:
(5*6)+(4*8)+(3*1)+(2*9)+(1*5)=88
88 % 10 = 8
So 681-95-8 is a valid CAS Registry Number.
