Overview

Cyano(cyanomercuriooxy)mercury (CAS 1335-31-5) is an organomercury explosive compound with extreme toxicity and high environmental hazard potential. This highly specialized organomercury compound represents one of the most hazardous chemical substances encountered in industrial chemistry, combining the severe toxicity of mercury compounds with explosive properties. The molecular structure C2Hg2N2O incorporates two mercury atoms linked through cyanide and oxygen bridges, creating a compound with exceptional instability and danger profile. With a molecular weight of 469.22 g/mol, this substance requires extraordinary safety precautions due to its classification as a Class 1.1 explosive material alongside acute toxicity ratings across multiple exposure routes. The compound exhibits extreme sensitivity to shock, friction, and heat, making handling procedures critically important for personnel safety. Its mercury content poses severe chronic health risks, particularly targeting the nervous system and kidneys, while the explosive nature demands specialized storage and transport protocols under ADR dangerous goods regulations. The acute toxicity classification across inhalation, dermal, and oral exposure routes, combined with specific target organ toxicity upon repeated exposure, necessitates comprehensive protective equipment and controlled atmosphere handling. Industrial applications are extremely limited due to safety concerns, primarily restricted to specialized explosive formulations and research applications where its unique properties are essential. Like other explosive mercury compounds such as hydroxylamine;nitric acid complexes, this substance finds use only in highly controlled military or specialized industrial contexts requiring extreme explosive sensitivity. OYSI maintains strict protocols for the procurement and distribution of this highly regulated substance, available exclusively to qualified industrial customers with appropriate safety certifications and handling capabilities.

What are the physicochemical properties of cyano(cyanomercuriooxy)mercury?

Cyano(cyanomercuriooxy)mercury is a mercury-containing compound with a molecular mass of 469.22 g/mol. The substance exhibits explosive properties classified as Expl. 1.1, indicating high sensitivity to impact, friction, or heat. Due to the presence of mercury atoms, it likely appears as a dense material. Specific physical properties such as melting point, solubility, and appearance require consultation of detailed safety data sheets, as handling requires specialized knowledge due to its hazardous classification.

What is cyano(cyanomercuriooxy)mercury used for?

Cyano(cyanomercuriooxy)mercury is primarily used in specialized industrial applications requiring organomercury compounds. Due to its explosive classification and high toxicity, its applications are highly restricted and typically limited to research purposes or very specific technical processes. The compound's use is heavily regulated due to mercury content and environmental concerns. Any industrial application must comply with strict safety protocols and regulatory requirements, making it suitable only for facilities with appropriate handling capabilities and permits.

How to handle cyano(cyanomercuriooxy)mercury safely?

Cyano(cyanomercuriooxy)mercury requires extreme safety precautions due to its explosive and toxic nature. Personnel must wear full protective equipment including respiratory protection, chemical-resistant gloves, and protective clothing. Work must be conducted in well-ventilated areas or fume hoods, away from ignition sources due to explosive properties. Only trained personnel should handle this substance, following strict protocols for organomercury compounds. Emergency procedures and mercury spill kits must be readily available during any handling operations.

How to store cyano(cyanomercuriooxy)mercury correctly?

Cyano(cyanomercuriooxy)mercury must be stored in specialized explosive storage facilities that meet safety requirements for Class 1.1 materials. Storage areas must be temperature-controlled, dry, and isolated from incompatible materials including oxidizers and heat sources.
