S-phenyl thiotrifluoroacetate, also known as phenylmethylsulfonyl trifluoroacetate, is an organic compound with the chemical formula C8H7F3O2S. It is a colorless to pale yellow liquid that is soluble in organic solvents. This chemical is primarily used as a reagent in organic synthesis, particularly in the preparation of various pharmaceuticals and agrochemicals. It is known for its ability to act as a sulfonylating agent, which can be used to introduce sulfonyl groups into molecules, a common modification in the synthesis of certain drugs and other chemical compounds. The compound is also recognized for its potential reactivity and should be handled with care due to its potential hazards.

2378-04-3 Usage

Check Digit Verification of cas no

The CAS Registry Mumber 2378-04-3 includes 7 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 4 digits, 2,3,7 and 8 respectively; the second part has 2 digits, 0 and 4 respectively.
Calculate Digit Verification of CAS Registry Number 2378-04:
(6*2)+(5*3)+(4*7)+(3*8)+(2*0)+(1*4)=83
83 % 10 = 3
So 2378-04-3 is a valid CAS Registry Number.

Synthetic Uses of Thio- and Selenoesters of Trifluoromethylated Acids. 1. Preparation of Trifluoromethyl Sulfides and Selenides

Billard, Thierry,Roques, Nicolas,Langlois, Bernard R.

, p. 3813 - 3820 (2007/10/03)

Trifluorothioacetates (CF3CO-S-R, from (CF3CO)2O and thiols) as well as trifluoromethanethio-or trifluoromethaneselenosulfonates (CF3SO2-Y-R; Y = S, Se; from CF3SO2Na, RYYR, and Br2) can be formally decarbonylated or desulfonylated, respectively, provided that they are photolyzed at 40°C in the presence of 1 equiv of the corresponding disulfide or diselenide. Trifluoromethyl sulfides or selenides are obtained, and the added disulfide (or diselenide) is recovered after reaction. In such a way, S-(trifluoromethyl)cysteine derivatives can be obtained.
