Tri-n-butylfluorphosphonium bromide (TBFPB) is a quaternary phosphonium salt with the chemical formula C12H28BrF3P. It is a colorless, viscous liquid that is soluble in water and organic solvents. TBFPB is widely used as a phase-transfer catalyst in various organic reactions, particularly in the synthesis of pharmaceuticals, agrochemicals, and other specialty chemicals. It facilitates the transfer of reactants between immiscible phases, such as between an aqueous and an organic phase, thereby enhancing reaction rates and selectivity. Due to its stability, non-toxicity, and ease of handling, TBFPB has become a popular choice for chemists in various research and industrial applications.

Check Digit Verification of cas no

The CAS Registry Mumber 80646-29-3 includes 8 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 5 digits, 8,0,6,4 and 6 respectively; the second part has 2 digits, 2 and 9 respectively.
Calculate Digit Verification of CAS Registry Number 80646-29:
(7*8)+(6*0)+(5*6)+(4*4)+(3*6)+(2*2)+(1*9)=133
133 % 10 = 3
So 80646-29-3 is a valid CAS Registry Number.
