Benzyltriphenylphosphonium chloride (BTPPC) is a phosphonium salt with the chemical formula C25H22ClP. It is a white crystalline solid that is soluble in water and organic solvents. BTPPC is widely used as a phase-transfer catalyst in organic synthesis, facilitating the transfer of reactants between aqueous and organic phases. It is particularly effective in reactions involving anions, such as halides and carboxylates, and is known for its stability and selectivity. The compound is also used in the preparation of other organophosphorus compounds and as a reagent in various chemical transformations. Its structure features a benzyl group attached to a triphenylphosphonium cation, which is counterbalanced by a chloride anion.

Check Digit Verification of cas no

The CAS Registry Mumber 2707-61-1 includes 7 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 4 digits, 2,7,0 and 7 respectively; the second part has 2 digits, 6 and 1 respectively.
Calculate Digit Verification of CAS Registry Number 2707-61:
(6*2)+(5*7)+(4*0)+(3*7)+(2*6)+(1*1)=81
81 % 10 = 1
So 2707-61-1 is a valid CAS Registry Number.
