Description
Copper(I) cyanide, also known as cuprous cyanide, is an inorganic compound with the chemical formula CuCN. It is a white, crystalline solid that is insoluble in water but soluble in potassium cyanide solution and slightly soluble in ammonia solution. Due to its high toxicity, it can release hydrogen cyanide gas when heated or in contact with acid.
Uses
Used in Electroplating Industry:
Copper(I) cyanide is used as a plating agent for depositing a thin layer of copper onto various surfaces. Its ability to form complexes with different molecules makes it suitable for this application, enhancing the quality and durability of the plated surfaces.
Used in Metallurgy:
In the metallurgical industry, copper(I) cyanide is used as a reagent in the extraction and refining of copper. Its complex-forming properties aid in the separation and purification processes, contributing to the production of high-purity copper.
Used as a Catalyst in Chemical Reactions:
Copper(I) cyanide is employed as a catalyst in various chemical reactions due to its ability to form stable complexes with reactants. This enhances the reaction rates and selectivity, making it a valuable component in the synthesis of certain compounds.
Production Method:
The production of copper(I) cyanide involves the reaction between copper(I) salts and cyanide. This process results in the formation of the desired compound, which can then be used in its various applications.
Check Digit Verification of cas no
The CAS Registry Mumber 544-92-3 includes 6 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 3 digits, 5,4 and 4 respectively; the second part has 2 digits, 9 and 2 respectively.
Calculate Digit Verification of CAS Registry Number 544-92:
(5*5)+(4*4)+(3*4)+(2*9)+(1*2)=73
73 % 10 = 3
So 544-92-3 is a valid CAS Registry Number.

METHOD FOR PREPARING LAMOTRIGINE AND ITS INTERMEDIATE 2,3-DICHLOROBENZOYL CHLORIDE
-
Page/Page column 14, (2010/11/29)
The invention relates to an improved method for preparing 3,5-diamino-6-(2,3-dichlorophenyl)-1,2,4-triazine, also commonly known as lamotrigine. The present invention also relates to a method for preparing the intermediate 2,3-dichlorobenzoyl chloride, which comprises the synthesis by photochlorination of 2,3-dichlorobenzotrichloride followed by hydrolysis thereof. Said 2,3-dichlorobenzoyl chloride intermediate is useful for preparing lamotrigine.
Electrochemistry of cyanocopper thiomolybdates and thiotungstates: Redox-based interconversion of species

[MoS4]2- and its 1:1 and 1:2 CuCN adducts [(CN)CuS2MoS2]2- and [(CN)CuS2MoS2Cu(CN)]2- each exhibit electrochemically reversible one-electron reductions in MeCN at fast scan rates (>500 mV s-1). At lower scan rates, the reduced adduct species are unstable to dissociation of CuCN, leading to interconversion of the three anions. The tungsten analogues show similar properties.
