| Hazard Information | Back Directory | [Potential Exposure]
Used as a microbiocide and algaecide in antifouling paints. Used as a laboratory chemical and for making other chemicals. Some formulations may be designated Restricted Use Pesticide (RUP). | [First aid]
Move victim to fresh air. Call 911 or emergency medical service. Ensure that medical personnel are aware of the material(s) involved and take precautions to protect themselves. Give artificial respiration if victim is not breathing. Do not use mouth-to-mouth method if victim ingested or inhaled the substance; give artificial respiration with the aid of a pocket mask equipped with a one-way valve or other proper respiratory medical device. Administer oxygen if breathing is difficult. Remove and isolate contaminated clothing and shoes. In case of contact with substance, immediately flush skin or eyes with running water for at least 20 minutes. For minor skin contact, avoid spreading material on unaffected skin. Keep victim warm and quiet. Effects of exposure (inhalation, ingestion, or skin contact) to substance may be delayed | [Shipping]
UN3439 Nitriles, solid, toxic, n.o.s., Hazard Class: 6.1; Labels: 6.1-Poisonous materials, Technical Name Required | [Incompatibilities]
Incompatible with oxidizers (chlorates, nitrates, peroxides, permanganates, perchlorates, chlorine, bromine, fluorine, etc.); contact may cause fires or explosions. Keep away from alkaline materials, strong bases, strong acids, oxoacids, epoxides | [Chemical Properties]
Copper(I) thiocyanate, CuSCN, [1111-67-7], MW 121.62, is a white powder when pure, but often the material of commerce is yellow. It is soluble in ammonia solution, alkali thiocyanate solutions, and diethyl ether, but it is only slightly soluble in water and dilute mineral acids. It is stable in air in the absence of moisture, but it slowly decomposes in the presence of moisture in air. It is used as an antifouling pigment. | [Waste Disposal]
Copper-containing soluble wastes can be concentrated through the use of ion exchange, reverse osmosis, or evaporators to the point where copper can be electrolytically removed and sent to a reclaiming firm. If recovery is not feasible, the copper can be precipitated through the use of caustics and the sludge deposited in a chemical waste landfill. Copper-containing wastes can be concentrated to the point where copper can be electrolytically removed and reclaimed. If recovery is not feasible, the copper can be precipitated by alkali; the cyanide destroyed by alkaline oxidation yielding a sludge which can be sent to a chemical waste landfill. In accordance with 40CFR165, follow recommendations for the disposal of pesticides and pesticide containers. Must be disposed properly by following package label directions or by contacting your local or federal environmental control agency, or by contacting your regional EPA office | [Characteristics]
Copper thiocyanate (CuSCN) is also a wide bandgap (3.6?eV) semiconductor and has a work function of about ?5.3?eV. The conductivity ranges between 10-2 and 10-3 S?cm-1, good stability, shows good transparency throughout the visible and near infrared spectrum. It has good chemical stability. It can be deposited through a solution processing approach at low temperature, making it compatible with flexible substrates. By using copper thiocyanate (CuSCN) instead of P3HT as the HTL, a higher device PCE was achieved. | [Uses]
In marine antifouling paints; in primer compositions for explosives industry. | [Preparation]
Copper(I) thiocyanate is prepared by the reaction of alkali metal thiocyanates with copper(I) chloride at 8090°C or by the reaction of copper(II) sulfate solutions with alkali metal thiocyanate in the presence of sulfite. It can also be prepared by precipitation from copper(II) salt solutions with hydrogen thiocyanate. | [General Description]

At least two polymorphs of cuprous thiocyanate have been characterized by X-ray crystallography. They both feature
copper(I) in a characteristic tetrahedral coordination geometry. The
sulfur end of the SCN- ligand is triply bridging so that the coordination sphere for copper is CuS3N. |
