Disulfide, ethyl trifluoromethyl, also known as ethyl trifluoromethyl disulfide, is a chemical compound with the molecular formula C3H5F3S2. It is a colorless liquid with a pungent odor and is used as a reagent in organic synthesis, particularly in the preparation of various sulfur-containing compounds. Disulfide, ethyl trifluoromethyl is characterized by its two sulfur atoms connected by a disulfide bond and a trifluoromethyl group attached to one of the sulfur atoms. Ethyl trifluoromethyl disulfide is sensitive to moisture and air, and it is typically stored under an inert atmosphere to prevent decomposition. Due to its reactivity, it is used in the synthesis of pharmaceuticals, agrochemicals, and other specialty chemicals.

Check Digit Verification of cas no

The CAS Registry Mumber 691-05-4 includes 6 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 3 digits, 6,9 and 1 respectively; the second part has 2 digits, 0 and 5 respectively.
Calculate Digit Verification of CAS Registry Number 691-05:
(5*6)+(4*9)+(3*1)+(2*0)+(1*5)=74
74 % 10 = 4
So 691-05-4 is a valid CAS Registry Number.

Simultaneous scission of C-S and S-S bonds of bis(trifluoromethyl)trisulfide by Grignard reagents

Munavalli, Shekar,Rossman, David I.,Rohrbaugh, Dennis K.,Ferguson, C. Parker,Szafraniec, Leonard J.

, p. 91 - 99 (2007/10/02)

Trifluoromethyl mono-, di- and tri-sulfides, and alkyl sulfides and disulfides, as well as dimerized products, are formed as a result of the simultaneous cleavage of the C-S and S-S bonds of bis(trifluoromethyl)trisulfide by Grignard reagents at -78 deg C.The formation of various products has been rationalized on the basis of the involvement of free radicals.

Chemistry of trifluoromethylsulfinyl fluoride. Trifluoromethylsulfinamides and trifluoromethylsulfinate esters

Sauer, Dennis T.,Shreeve, Jean'ne M.

, p. 358 - 362 (2007/10/12)

Trifluoromethylsulfinate esters and trifluoromethylsulfinamides result when trifluoromethylsulfinyl fluoride reacts with alcohols and amines. Mercaptans with CF3S(O)F do not yield the expected thiosulfinates but rather mixed disulfides. The methylene protons of CF3CH2OS(O)CF3 and CH3CH2OS(O)CF3 are magnetically nonequivalent giving rise to ABM3X3 nmr spectra. The new compounds CF3S(O)OCH3, CF3S(O)OCH2CH3, CF3S(O)OCH2CF3, CF3S(O)N(CH2CH3)2, CF3S(O)N(CH3)2, (CF3S(O))2NCH3, and CF3S(O)NH2 are slightly volatile, colorless liquids.
