Tris-(2,6-diisopropylphenyl)-borat, also known as BIPB, is a boron-containing compound with the chemical formula C24H33B. It is a colorless, crystalline solid that is soluble in organic solvents. BIPB is a versatile reagent in organic synthesis, particularly in the formation of carbon-carbon bonds and the synthesis of various heterocycles. It acts as a Lewis acid catalyst, facilitating reactions through the coordination of its boron center with electron-rich substrates. The bulky diisopropylphenyl groups on the boron atom provide steric hindrance, which can influence the selectivity of the reactions it catalyzes. BIPB is also known for its stability and ease of handling, making it a popular choice in academic and industrial settings for a range of chemical transformations.
The CAS Registry Mumber 22238-31-9 includes 8 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 5 digits, 2,2,2,3 and 8 respectively; the second part has 2 digits, 3 and 1 respectively. Calculate Digit Verification of CAS Registry Number 22238-31: (7*2)+(6*2)+(5*2)+(4*3)+(3*8)+(2*3)+(1*1)=79 79 % 10 = 9 So 22238-31-9 is a valid CAS Registry Number.
