Dipropyl-dipent-1-inyl-zinn, also known as dipropyl-dipent-1-inyl-zinc, is a chemical compound with the formula (C5H9)2Zn. It is an organozinc compound that consists of two pent-1-ynyl groups and a zinc atom. Dipropyl-dipent-1-inyl-zinn is primarily used as a reagent in organic synthesis, particularly in the formation of carbon-carbon bonds through the Negishi coupling reaction. The Negishi coupling is a cross-coupling reaction that involves the reaction of an organozinc reagent with an organic halide, leading to the formation of new carbon-carbon bonds. Dipropyl-dipent-1-inyl-zinc is synthesized by reacting zinc metal with two equivalents of pent-1-ynyl bromide in the presence of a suitable solvent. It is a colorless liquid and is sensitive to air and moisture, requiring careful handling under an inert atmosphere.

5054-43-3 Usage
Check Digit Verification of cas no
The CAS Registry Mumber 5054-43-3 includes 7 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 4 digits, 5,0,5 and 4 respectively; the second part has 2 digits, 4 and 3 respectively.Calculate Digit Verification of CAS Registry Number 5054-43:
(6*5)+(5*0)+(4*5)+(3*4)+(2*4)+(1*3)=73
73 % 10 = 3
So 5054-43-3 is a valid CAS Registry Number.
