Selanylidenenickel

Selanylidenenickel is an inorganic compound with the molecular formula NiSe and CAS number 1314-05-2. It represents a binary compound of nickel and selenium with a molecular weight of 137.66 g/mol. This material is classified as a highly hazardous substance with carcinogenic properties (Category 1A) and poses significant risks to human health and the environment. It requires specialized handling procedures and is subject to strict regulatory controls due to its dangerous nature.

Selanylidenenickel appears as a solid crystalline material at room temperature. As a nickel selenide compound, it typically exhibits metallic luster and semiconductor properties. The compound has limited solubility in water but may react with acids. Its physicochemical behavior is influenced by the presence of both nickel and selenium atoms in its structure, contributing to its specific electronic and thermal properties that make it suitable for specialized industrial applications.

Selanylidenenickel is primarily used in specialized industrial applications including semiconductor manufacturing, electronic components, and advanced materials research. Its unique electronic properties make it valuable in the production of photovoltaic devices and thermoelectric materials. Due to its hazardous classification, its use is restricted to professional industrial settings with appropriate safety controls and environmental protection measures. Applications require specialized expertise and compliance with strict safety protocols.

Selanylidenenickel requires extensive personal protective equipment including respiratory protection, chemical-resistant gloves, and protective clothing due to its carcinogenic and sensitizing properties. Work must be conducted in well-ventilated areas or under controlled atmosphere conditions. Personnel must be trained in hazardous material handling and emergency procedures. Skin contact must be avoided at all costs due to sensitization risks, and inhalation protection is mandatory to prevent systemic toxicity effects.

Selanylidenenickel must be stored in tightly sealed containers in a cool, dry, well-ventilated area away from incompatible materials. Storage areas should be equipped with appropriate containment systems and restricted access due to the carcinogenic nature of the material. The compound should be kept away from acids, oxidizing agents, and moisture. Secondary containment is recommended, and storage facilities must comply with local regulations for carcinogenic substances and environmental protection requirements.

Immediate medical attention is required for any contact with selanylidenenickel. In case of skin contact, remove contaminated clothing and wash affected area thoroughly with soap and water for at least 15 minutes. If inhaled, move the person to fresh air immediately and seek medical care. For eye contact, rinse with clean water for at least 15 minutes. Due to its carcinogenic properties, all exposure incidents must be documented and reported to occupational health services for proper medical follow-up.

Selanylidenenickel disposal must be handled by licensed hazardous waste management companies due to its carcinogenic classification and environmental toxicity. The material cannot be disposed of through regular waste streams and requires specialized treatment methods. Disposal must comply with local and EU regulations for carcinogenic substances and aquatic pollutants. All disposal activities must be properly documented, and waste containers must be clearly labeled with appropriate hazard information before collection by authorized waste management services.

Selanylidenenickel is classified as ADR Class 9 (Miscellaneous dangerous goods), Packing Group III for transportation purposes. Transport requires appropriate packaging, labeling with GHS pictograms (GHS08, GHS07, GHS09), and accompanying documentation including safety data sheets. Shipments must comply with dangerous goods transport regulations and be handled by carriers qualified for hazardous materials. Special precautions are needed to prevent package damage and environmental release during transit.

Selanylidenenickel is subject to extensive European regulations under REACH and CLP due to its carcinogenic Category 1A classification. The substance requires safety data sheets, hazard communication, and may be subject to authorization procedures. Its classification as STOT RE 1 and aquatic toxicity categories impose additional restrictions on use and handling. Companies using this material must comply with occupational health regulations, environmental protection requirements, and may need specialized permits depending on the application and quantities involved.

Selanylidenenickel is available through specialized chemical distributors in Europe, including OYSI, which supplies high-quality chemical products to industrial customers. Due to its hazardous classification, procurement requires proper documentation, safety protocols, and compliance with regulatory requirements. OYSI provides technical support and ensures proper packaging, labeling, and documentation for safe delivery. Customers must demonstrate appropriate handling capabilities and regulatory compliance before purchase approval for this controlled substance.
