Tripropylallylstannane, also known as (allyl)tri-n-propylstannane, is an organostannane compound with the chemical formula C9H21Sn. It is a colorless liquid that is soluble in organic solvents and is commonly used as a reagent in organic synthesis, particularly in the formation of carbon-carbon bonds through the Stille coupling reaction. This reaction involves the cross-coupling of an organostannane with an organohalide or organotriflate, facilitated by a palladium catalyst. Tripropylallylstannane is also used in the synthesis of various organic compounds, such as pharmaceuticals and natural products, due to its ability to act as a nucleophile and participate in various types of reactions, including cross-coupling, reduction, and radical reactions.
The CAS Registry Mumber 40438-80-0 includes 8 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 5 digits, 4,0,4,3 and 8 respectively; the second part has 2 digits, 8 and 0 respectively. Calculate Digit Verification of CAS Registry Number 40438-80: (7*4)+(6*0)+(5*4)+(4*3)+(3*8)+(2*8)+(1*0)=100 100 % 10 = 0 So 40438-80-0 is a valid CAS Registry Number.
