Triphenylphosphoniomethansulfonat, also known as triphenylmethylphosphonium methanesulfonate or PPh3MeSO3, is a phosphonium salt that serves as a versatile reagent in organic chemistry. It is characterized by its ability to act as a source of the triphenylmethyl carbocation (Ph3C+), which is a highly reactive intermediate. This reagent is particularly useful in the formation of carbon-carbon bonds, such as in the Simmons-Smith reaction for the synthesis of cyclopropanes. Triphenylphosphoniomethansulfonat is also employed in the generation of other carbocations and in various substitution and rearrangement reactions. Its stability and ease of preparation make it a valuable tool in synthetic chemistry, although it should be handled with care due to its sensitivity to moisture and air.

54378-80-2 Usage
Check Digit Verification of cas no
The CAS Registry Mumber 54378-80-2 includes 8 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 5 digits, 5,4,3,7 and 8 respectively; the second part has 2 digits, 8 and 0 respectively.Calculate Digit Verification of CAS Registry Number 54378-80:
(7*5)+(6*4)+(5*3)+(4*7)+(3*8)+(2*8)+(1*0)=142
142 % 10 = 2
So 54378-80-2 is a valid CAS Registry Number.
