Physical Properties

Stability

Cyanamide is an instable substance that can react with itself or other reactants releasing potentially dangerous exothermal heat. Dimerization of Cyanamide in alkaline environment gives dicyandiamide, while addition of water in acidic media leads to urea. To prevent from these degradation reactions, a buffering stabilizer is added to all Cyanamide products. This stabilizer ensures a maximum quality lifetime and safe transport and storage. Cyanamide is stable in the pH range from 4 to 6 with optimum stability at pH 4.0 to 4.5. Avoid all contact with alkaline or acidic compounds as long it is not the anticipated reaction under controlled conditions. Uncontrolled heat-up of solid Cyanamide F1000 can lead to amaximum decomposition temperature of more than 500  °C, with release of toxic gases and potentially severe damages.

Physiologic Properties and Toxicology

Pure cyanamide is toxic if swallowed and harmful in contact with skin. It is organ toxic with long-term effects. It is suspect of causing cancer, damaging fertility and damaging the unborn child. Cyanamide is corrosive to the skin and eyes. It has sensitizing properties and is capable to cause eczema-like rashes even after short-term skin contact. Harmful to aquatic life with long lasting effects

Solubility

Cyanamide is highly soluble in water, aliphatic alcohols, ethers, esters and amides. It is insoluble in aliphatic hydrocarbons. Ketones, amines and acids are not suitable as solvents. The Cyanamide/water eutectic solidifies at -16.6 °C.

Reactivity

Cyanamide may be regarded as the amide of cyanic acid or as the nitrile of carbamic acid. The difunctional molecule is capable of reacting as a nucleophile at the amino group or as an electrophile at the cyano group. Many reactions include both reactive sites forming heterocycles.
