Cyanamide

Cyanamide is an organic compound with the chemical formula CH2N2 and molecular weight of 42.04 g/mol. It is a nitrogen-containing chemical that serves as an important industrial intermediate and agricultural product. This substance is classified as hazardous due to its corrosive properties, potential carcinogenic effects, and reproductive toxicity. Cyanamide requires careful handling due to its multiple health hazards including acute toxicity and skin sensitization properties.

Cyanamide is typically a white crystalline solid at room temperature with hygroscopic properties, meaning it readily absorbs moisture from air. The compound is highly soluble in water and polar solvents, forming alkaline solutions. It has a characteristic ammonia-like odor and can decompose upon heating or in the presence of acids. The substance is stable under normal conditions but can polymerize or decompose when exposed to high temperatures or certain catalysts.

Cyanamide is primarily used as an agricultural chemical, particularly as a plant growth regulator and soil treatment agent in viticulture and horticulture. It serves as an important intermediate in the synthesis of pharmaceuticals, including guanidine derivatives and other nitrogen-containing compounds. The substance is also utilized in the production of melamine, dicyandiamide, and various organic chemicals. Additionally, it finds applications in the manufacturing of plastics, resins, and specialty chemicals.

Cyanamide requires extensive personal protective equipment including chemical-resistant gloves, safety goggles, and full-face respiratory protection due to its corrosive and toxic nature. Workers must wear acid-resistant clothing and work in well-ventilated areas or under fume extraction systems. Avoid skin and eye contact completely, as the substance causes severe burns and permanent eye damage. Handle only with proper training and ensure emergency shower and eyewash stations are readily accessible.

Cyanamide must be stored in tightly sealed, corrosion-resistant containers in a cool, dry, well-ventilated area away from heat sources and direct sunlight. Keep separated from acids, oxidizing agents, and incompatible materials to prevent dangerous reactions. Storage areas should be equipped with appropriate spill containment measures and restricted access. Maintain temperatures below 25°C and protect from moisture to prevent decomposition. Regular container inspection is essential due to the corrosive nature of the substance.

Cyanamide contact requires immediate emergency response due to its severe corrosive properties. For skin contact, immediately flush with copious amounts of water for at least 15 minutes while removing contaminated clothing. In case of eye exposure, rinse continuously with water for at least 15 minutes and seek immediate medical attention. If inhaled, move the person to fresh air and provide oxygen if breathing is difficult. Never induce vomiting if ingested and obtain emergency medical care immediately.

Cyanamide disposal must comply with local and European waste regulations as it is classified as hazardous waste. The substance cannot be disposed of in regular waste streams and requires specialized treatment at authorized hazardous waste facilities. Small quantities can be neutralized carefully under controlled conditions by qualified personnel before disposal. Container disposal must also follow hazardous waste protocols. Always consult local environmental authorities and waste management companies for specific disposal requirements and procedures.

Cyanamide is classified under ADR regulations as Class 8 (corrosive substances), Packing Group III, requiring appropriate hazardous goods packaging and labeling. Transportation must comply with dangerous goods regulations including proper packaging, marking, and documentation. Vehicles must display appropriate hazard placards and drivers require ADR training certification. The substance must be secured to prevent movement during transport and separated from incompatible materials. Emergency response information must accompany all shipments.

Cyanamide is subject to comprehensive European chemical regulations under REACH and CLP, requiring safety data sheets and hazard classification. The substance is classified as Category 2 carcinogen and reproductive toxicant, triggering strict workplace exposure limits and authorization requirements. It falls under dangerous goods regulations for transport and storage. Users must comply with occupational health and safety directives, and industrial emissions may be regulated under environmental protection laws depending on usage quantities and applications.

Cyanamide is available through OYSI, a specialized European distributor of technical chemicals serving industrial customers across Europe. As a hazardous substance requiring expert handling, it is essential to source from qualified suppliers who provide proper documentation, safety data sheets, and regulatory compliance support. OYSI ensures reliable supply chain management and technical support for industrial applications. Due to regulatory requirements, purchases typically require end-user declarations and appropriate licensing for handling hazardous chemicals.
