Dipropyl-di-hex-1-inyl-zinn, also known as di-n-propyl-di-n-hex-1-inylzinc, is an organozinc compound with the chemical formula C18H36Zn. It is a colorless liquid at room temperature and is highly sensitive to air and moisture. Dipropyl-di-hex-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 reactivity of di-n-propyl-di-n-hex-1-inylzinc is attributed to the strong nucleophilic nature of the zinc center, which allows it to participate in various cross-coupling reactions with a wide range of electrophiles. Due to its sensitivity, it is crucial to handle Dipropyl-di-hex-1-inyl-zinn under an inert atmosphere, such as nitrogen or argon, to prevent unwanted side reactions.
The CAS Registry Mumber 5054-44-4 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 4 respectively. Calculate Digit Verification of CAS Registry Number 5054-44: (6*5)+(5*0)+(4*5)+(3*4)+(2*4)+(1*4)=74 74 % 10 = 4 So 5054-44-4 is a valid CAS Registry Number.
