Description
Thiocyanic acid, also known as HSCN, is a hydracid derived from cyanic acid with the oxygen atom replaced by a sulfur atom. It is an unstable gas with unique chemical properties.
Uses
Used in Chemical Synthesis:
Thiocyanic acid is used as a reagent in the chemical synthesis of various compounds, such as thiourea, dyes, and pharmaceuticals. Its ability to form thiocyanate salts with metal ions makes it a versatile building block in the chemical industry.
Used in Analytical Chemistry:
Thiocyanic acid is utilized as an analytical reagent for the detection and determination of metal ions, particularly in the analysis of heavy metals like gold, silver, and mercury. Its high affinity for these metals allows for accurate and sensitive measurements.
Used in Agriculture:
In the agricultural industry, thiocyanic acid is employed as a component in the formulation of certain pesticides and herbicides. Its ability to inhibit specific metabolic pathways in pests and weeds contributes to its effectiveness in these applications.
Used in Metallurgy:
Thiocyanic acid is used in the metallurgical industry for the extraction and purification of metals, such as gold and silver. Its ability to form stable complexes with these metals aids in their separation and recovery from ores.
Used in Environmental Applications:
Thiocyanic acid is employed in environmental applications for the treatment of wastewater and the removal of heavy metal contaminants. Its strong chelating properties enable the efficient removal of toxic metals from industrial effluents, thus reducing their environmental impact.
Check Digit Verification of cas no
The CAS Registry Mumber 463-56-9 includes 6 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 3 digits, 4,6 and 3 respectively; the second part has 2 digits, 5 and 6 respectively.
Calculate Digit Verification of CAS Registry Number 463-56:
(5*4)+(4*6)+(3*3)+(2*5)+(1*6)=69
69 % 10 = 9
So 463-56-9 is a valid CAS Registry Number.

Photolysis of isothiocyanic acid HNCS in low-temperature matrices. Infrared detection of HSCN and HSNC isomers
Wierzejewska, Maria,Mielke, Zofia
, p. 227 - 234 (2001)
A combination of matrix isolation technique and Fourier transform infrared spectroscopy has been used to study the low-temperature photochemistry of isothiocyanic acid HNCS. Near UV photolysis with a medium-pressure mercury lamp of the matrix isolated HNCS/DNCS precursor in nitrogen and argon led to the formation of two unobserved, so far, isomers: thiocyanic acid HSCN and isothiofulminic acid HSNC and their deuterated analogs. Both species are formed as primary products presumably via two reaction channels: formation of the [HNCS] and hydrogen migration leading to the HSCN molecule and formation of the [HNCS] followed by rearrangement to HSCN and HSNC species.
