FAQ

What is Cyanamide (CAS: 420-04-2)?

Cyanamide is a chemical compound with the formula CH₄N₂. It is a white crystalline solid that is highly reactive and can be unstable under certain conditions. Cyanamide is known for its ability to release ammonia and is commonly used in various industrial and chemical applications due to its unique reactivity and properties.

What are the main uses of Cyanamide (CAS: 420-04-2)?

Cyanamide is primarily used in the production of acrylonitrile, which is a key component in synthetic fibers and plastics. It also finds applications in pharmaceuticals, as a precursor for certain drugs, and in the synthesis of other nitrogen-containing compounds. Additionally, it is used in the manufacture of dyes and as a reducing agent in some chemical processes.

Is Cyanamide (CAS: 420-04-2) safe?

Cyanamide is considered hazardous and requires careful handling. It can cause irritation to the skin, eyes, and respiratory system. Safety standards emphasize the use of protective equipment, such as gloves and goggles, and proper ventilation. It should be stored in a secure, well-ventilated area away from moisture and incompatible materials to minimize risks.

How should Cyanamide (CAS: 420-04-2) be stored?

Cyanamide should be stored in a cool, dry, and dark place, ideally at temperatures below 25°C. It is sensitive to moisture and should be kept in a sealed, airtight container. Storage away from light and incompatible substances is recommended to ensure stability and safety. Regular monitoring of storage conditions is essential to prevent degradation or hazardous reactions.
