Tris-butylamino-borane, also known as tris(butylamine)borane or Bu3N·BH3, is a colorless, hygroscopic, and highly flammable liquid that serves as a reducing agent in organic chemistry. It is commonly used for the reduction of carbonyl compounds, such as aldehydes and ketones, to their corresponding alcohols. The compound is prepared by the reaction of butylamine with borane, and it is often employed in the presence of a proton source, such as water or an alcohol, to facilitate the reduction process. Due to its reactivity and sensitivity to moisture, tris-butylamino-borane must be handled with care and stored under an inert atmosphere.
The CAS Registry Mumber 4254-93-7 includes 7 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 4 digits, 4,2,5 and 4 respectively; the second part has 2 digits, 9 and 3 respectively. Calculate Digit Verification of CAS Registry Number 4254-93: (6*4)+(5*2)+(4*5)+(3*4)+(2*9)+(1*3)=87 87 % 10 = 7 So 4254-93-7 is a valid CAS Registry Number.
