Trifluoromethylcarbonocyanidimidic acid trimethylsilyl ester, also known as TMSCN, is a chemical compound with the molecular formula C4H9F3NSi. It is a colorless liquid that is widely used as a reagent in organic synthesis, particularly in the preparation of nitriles and amides. TMSCN is a stable and easily handled alternative to hydrogen cyanide (HCN), offering improved safety and convenience in the laboratory. It is also used in the synthesis of various pharmaceuticals, agrochemicals, and other specialty chemicals. The compound is known for its reactivity with electrophiles, such as aldehydes and ketones, to form imines, which can be further converted to nitriles or amides. Its trimethylsilyl group provides stability and facilitates the release of the cyanide ion in reactions, making it a valuable tool in synthetic chemistry.

70856-22-3 Usage
Check Digit Verification of cas no
The CAS Registry Mumber 70856-22-3 includes 8 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 5 digits, 7,0,8,5 and 6 respectively; the second part has 2 digits, 2 and 2 respectively.Calculate Digit Verification of CAS Registry Number 70856-22:
(7*7)+(6*0)+(5*8)+(4*5)+(3*6)+(2*2)+(1*2)=133
133 % 10 = 3
So 70856-22-3 is a valid CAS Registry Number.
