Copper(1+) thiocyanate

Copper(1+) thiocyanate is an inorganic chemical compound with the molecular formula CCuNS and CAS number 1111-67-7. This copper salt contains copper in its +1 oxidation state bound to thiocyanate ions. With a molecular weight of 121.63 g/mol, it appears as a crystalline solid and is classified as hazardous to aquatic environments, requiring careful handling in industrial applications.

Copper(1+) thiocyanate is a solid crystalline compound at room temperature, typically appearing as white to pale yellow crystals. It has limited solubility in water but may dissolve in certain organic solvents. The compound is relatively stable under normal conditions but can decompose upon heating, releasing toxic gases including hydrogen cyanide and sulfur oxides.

Copper(1+) thiocyanate is primarily used in analytical chemistry as a reagent for detecting and quantifying various substances. It serves applications in electroplating processes, as a catalyst in organic synthesis reactions, and in specialized industrial processes requiring copper-thiocyanate chemistry. The compound is also utilized in research laboratories for chemical analysis and synthesis work.

Copper(1+) thiocyanate requires careful handling with appropriate personal protective equipment including safety goggles, chemical-resistant gloves, and lab coats. Work should be conducted in well-ventilated areas or under fume hoods to prevent inhalation. Avoid skin and eye contact, and never ingest the material. Emergency eyewash stations and safety showers should be readily accessible when working with this compound.

Copper(1+) thiocyanate should be stored in a cool, dry, well-ventilated area away from direct sunlight and heat sources. Keep containers tightly sealed to prevent moisture absorption and contamination. Store separately from strong acids, bases, and oxidizing agents to prevent dangerous reactions. Ensure storage areas have appropriate spill containment measures due to its aquatic toxicity classification.

Copper(1+) thiocyanate exposure requires immediate action depending on the route of contact. For skin contact, remove contaminated clothing and rinse affected areas with plenty of water for at least 15 minutes. If eye contact occurs, flush immediately with water and seek medical attention. In case of inhalation, move to fresh air immediately and consult medical personnel if symptoms develop.

Copper(1+) thiocyanate disposal must comply with local environmental regulations due to its aquatic toxicity classification under GHS09. The compound cannot be disposed of through regular waste streams and requires specialized hazardous waste treatment. Contact licensed waste disposal companies experienced in handling copper compounds and cyanide-containing materials for proper treatment and disposal according to regulatory requirements.

Copper(1+) thiocyanate is classified under ADR Class 9 (Miscellaneous dangerous goods), Packing Group III for transportation purposes. This classification requires appropriate packaging, labeling, and documentation during shipping. Packages must display proper hazard labels and shipping names, and transport vehicles need suitable safety equipment. Consult current ADR regulations for specific packaging and documentation requirements.

Copper(1+) thiocyanate is subject to various chemical regulations including REACH registration requirements in Europe and CLP classification standards. The compound is classified as Aquatic Acute 1 and Aquatic Chronic 1, requiring specific labeling with GHS09 pictograms and 'Warning' signal words. It is not currently listed as a Substance of Very High Concern (SVHC) under REACH regulations.
