812-12-4 Usage
General Description
Trifluoromethanesulfinyl fluoride, also known as CF3SO2F, is a highly reactive and toxic chemical compound used in various industrial applications such as pharmaceuticals, agrochemicals, and materials science. It is a colorless, odorless gas that is extremely flammable and must be handled with caution due to its potential to cause skin and eye irritation, respiratory issues, and central nervous system effects. Trifluoromethanesulfinyl fluoride is used as a fluorination reagent in organic synthesis to introduce fluorine atoms into organic molecules, which can enhance their biological activity or stability. Its strong oxidizing properties make it a valuable tool in the synthesis of complex organic compounds and in the production of specialty chemicals. However, due to its hazardous nature, proper safety measures must be followed when handling, storing, and using trifluoromethanesulfinyl fluoride in laboratory and industrial settings.
Check Digit Verification of cas no
The CAS Registry Mumber 812-12-4 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 2 respectively; the second part has 2 digits, 1 and 2 respectively.
Calculate Digit Verification of CAS Registry Number 812-12:
(5*8)+(4*1)+(3*2)+(2*1)+(1*2)=54
54 % 10 = 4
So 812-12-4 is a valid CAS Registry Number.

Oxidative halogenation of CF3SN(SiMe3)2 with F2 or Cl2 leads to CF3S(X)=NX (X=F, Cl) (2a, b).During the chlorination process CF3S(Cl)=NSiMe3 (3a) was isolated and characterized as an intermediate.It reacts with CF3SCl to give CF3S(Cl)=NSCF3 (3b) which was also obtained from (CF3S)2NH and Cl2 at -60 deg C.Similarly, CF3S(F)=NSCF3 (3c) was synthesized from (CF3S)2NH and F2 or from CF3SF3 and CF3SNH2. 3a-c decompose already at temperatures 5a, b).Analoguosly, CF3SN=S=NSCF3 (4b) reacts with cyclopentadiene to give 5c.Ringopening takes place during the reaction of + Cl- (6) with Hg(SCF3)2 with formation of CF3SSN=S=NSSCF3 (7) which was also obtained from (CF3SS)2NH and (ClSN)3 in the presence of pyridine.Physical and spectroscopic data of the compounds are reported.
