Triphenylphosphine-ethoxycarbonylborane, also known as (EtO)3PBH2, is a complex organoborane reagent widely used in organic synthesis. It is formed by the combination of triphenylphosphine (PPh3), ethoxycarbonyl (EtO), and borane (BH3). This reagent is particularly effective in various chemical reactions, such as the reduction of carbonyl compounds to alcohols, the formation of carbon-carbon bonds through the addition of organoboranes to alkenes, and the hydroboration of alkenes. Its stability, reactivity, and selectivity make it a valuable tool in the synthesis of complex organic molecules, including pharmaceuticals and natural products.
The CAS Registry Mumber 78315-29-4 includes 8 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 5 digits, 7,8,3,1 and 5 respectively; the second part has 2 digits, 2 and 9 respectively. Calculate Digit Verification of CAS Registry Number 78315-29: (7*7)+(6*8)+(5*3)+(4*1)+(3*5)+(2*2)+(1*9)=144 144 % 10 = 4 So 78315-29-4 is a valid CAS Registry Number.
