Sulfocyanic acid

CAS: 463-56-9
Molecular Formula: HSCN
Molecular Weight: 59.09
Product description:Volatile, with a strong smell of acid liquid, crystal precipitation under 0 ℃, soluble in water, is strongly acidic. Dilute solution is stable. Heating or hydrogen and sulfur acid and inorganic acid, is decomposed into all sorts of cyanide, and olefins reaction generated ester. Formula for HSCN, structural formula for H - S - C ≡ N. Thiocyanate is another isomer is H - N = C = S. Free acid is a mixture of two tautomerism, is unable to separate, but its ester has two forms. (is) ester thiocyanate R - S - C ≡ N is usually liquid with onion smell. Isothiocyanates R - N = C = S often called mustard oil, is a liquid with abnormal odour. Toxic, thiocyanate to eyes and skin and exciting role. And the generation of two valence metal salt formula for M (SCN) 2 (M on behalf of two valence metal ions, such as magnesium 2 +, Ca2 +, Zn2 +, etc.).Can be used for preparing thiocyanate, ester, various sulfur cyanide and cyanide.
