Thiocyanic acid, trifluoromethyl ester, also known as trifluoromethyl thiocyanate, is a chemical compound with the formula CF3SCN. It is a colorless, volatile liquid that is soluble in organic solvents. Thiocyanic acid, trifluoromethyl ester is synthesized by the reaction of trifluoroacetic acid with potassium thiocyanate or by the reaction of carbon tetrachloride with potassium thiocyanate in the presence of aluminum chloride. Thiocyanic acid, trifluoromethyl ester, is an important intermediate in the synthesis of various pharmaceuticals, agrochemicals, and other organic compounds. It is also used as a reagent in organic synthesis and as a precursor for the preparation of other fluorinated compounds. Due to its reactivity and potential toxicity, it should be handled with care and used in well-ventilated areas.

690-24-4 Usage

Check Digit Verification of cas no

The CAS Registry Mumber 690-24-4 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 0 respectively; the second part has 2 digits, 2 and 4 respectively.
Calculate Digit Verification of CAS Registry Number 690-24:
(5*6)+(4*9)+(3*0)+(2*2)+(1*4)=74
74 % 10 = 4
So 690-24-4 is a valid CAS Registry Number.

On the Reactions of CF3SF4Cl, (CF3)2SF2, SF4, and OSCl2 with Trimethylsilyl Cyanide

Kumar, Ramesh C.,Shreeve, Jean'ne M.

, p. 1407 - 1410 (2007/10/02)

A moderately stable hexacoordinated sulfur(VI) compound with four different kinds of ligands, CF3SF2(CN)2Cl, results when CF3SF4Cl is reacted with (CH3)3SiCN.The latter compound also gives F2S(CN)2 and (CF3)2S(CN)2 with SF4 and (CF3)2SF2, respectively.These tetracoordinated sulfur(IV) compounds decompose rapidly at 25 deg C but are stable at lower temperatures.With OSCl2 and SCl2, the white solids OS(CN)2 and S(CN)2 result.This provides a new, convenient route to S(CN)2. - Keywords: (Trifluoromethyl)chlorodicyanodifluorosulfur(VI), Dicyanodifluorosulfur(IV), Dicyanobis(trifluormethyl)sulfur(IV), Thionyl Cyanide
