Trimethylsilyl trifluoromethanesulfonate, also known as trimethylsilyl triflate or TMSOTf, is a colorless, volatile, and moisture-sensitive reagent used in organic synthesis. It is a derivative of trifluoromethanesulfonic acid, with a trimethylsilyl group replacing the hydrogen atom. TMSOTf is a powerful Lewis acid and a widely used catalyst in various chemical reactions, such as esterification, etherification, and rearrangements. It is particularly effective in promoting the formation of carbon-carbon bonds and can be used to activate alcohols, carboxylic acids, and other functional groups. Due to its reactivity, TMSOTf must be handled with care and stored under anhydrous conditions to prevent hydrolysis.

88248-68-4 Usage

Check Digit Verification of cas no

The CAS Registry Mumber 88248-68-4 includes 8 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 5 digits, 8,8,2,4 and 8 respectively; the second part has 2 digits, 6 and 8 respectively.
Calculate Digit Verification of CAS Registry Number 88248-68:
(7*8)+(6*8)+(5*2)+(4*4)+(3*8)+(2*6)+(1*8)=174
174 % 10 = 4
So 88248-68-4 is a valid CAS Registry Number.
