Bis(trifluoromethylthio)methane, also known as 1,1-bis(trifluoromethylthio)methane or CF3S-CH2-SCF3, is an organosulfur compound characterized by its two trifluoromethylthio groups (CF3S) attached to a central methane (CH2) molecule. This colorless liquid is a valuable intermediate in the synthesis of various pharmaceuticals, agrochemicals, and other specialty chemicals. It is known for its unique reactivity, stability, and ability to form a wide range of sulfur-containing compounds. Bis(trifluoromethylthio)methane is typically produced through the reaction of trifluoromethylthiirane with formaldehyde and is used in the preparation of complex organic molecules, highlighting its importance in the field of organic chemistry.

Check Digit Verification of cas no

The CAS Registry Mumber 819-67-0 includes 6 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 3 digits, 8,1 and 9 respectively; the second part has 2 digits, 6 and 7 respectively.
Calculate Digit Verification of CAS Registry Number 819-67:
(5*8)+(4*1)+(3*9)+(2*6)+(1*7)=90
90 % 10 = 0
So 819-67-0 is a valid CAS Registry Number.

Reactions of trifluoromethylthiocopper with halomethanes

Munavalli,Rossman,Rohrbaugh,Ferguson,Durst

, p. 7 - 13 (1996)

The reaction of trifluoromethylthiocopper with halomethanes, namely di-and triiodo-, dibromodichloro-, dibromochlorofluoro-, dibromo-difluoro-, bromochlorofluoro-, phenyltrichloro-, bromocyano-and dibromofluoro-methanes, has been investigated in detail. In addition to the expected compounds, the formation of unusual products such as bis (trifluoromethyl) trithiocarbonate, dimethyl (trifluoromethylthio) benzene, bis (trifluoromethylthio) fluoromethane, (trifluoromethylthio) carbonyl fluoride, carbon disulfide, carbon tetrachloride, trifluoromethylthio-benzoate, etc. was observed. In some cases, bis (trifluoromethylthio) mercury has been used instead of trifluoromethylthiocopper. The mechanism of formation of the various products and their mass spectral fragmentation behavior are described.
