Zinc, bromo-2-butenyl-, also known as 2-butenylzinc bromide or 2-bromoallylzinc, is an organozinc compound with the chemical formula C4H6BrZn. It is a colorless liquid that is sensitive to air and moisture, and it is commonly used as a reagent in organic synthesis, particularly in the formation of carbon-carbon bonds through the Negishi coupling reaction. This reaction involves the cross-coupling of an organozinc reagent with an organic halide in the presence of a transition metal catalyst, leading to the formation of new carbon-carbon bonds. The compound is typically prepared by the reaction of 2-bromoallyl bromide with zinc metal in a suitable solvent, and it is used as a building block in the synthesis of various organic compounds, including pharmaceuticals and natural products. Due to its reactivity, it is important to handle Zinc, bromo-2-butenyl- under an inert atmosphere or in a glovebox to prevent unwanted side reactions.

14735-44-5 Usage
Check Digit Verification of cas no
The CAS Registry Mumber 14735-44-5 includes 8 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 5 digits, 1,4,7,3 and 5 respectively; the second part has 2 digits, 4 and 4 respectively.Calculate Digit Verification of CAS Registry Number 14735-44:
(7*1)+(6*4)+(5*7)+(4*3)+(3*5)+(2*4)+(1*4)=105
105 % 10 = 5
So 14735-44-5 is a valid CAS Registry Number.
