Description of key information

Sodium cyanide behaves as an inorganic substance. By reading across from hydrogen cyanide, the partition coefficient is -0.25; this is relevant for soluble sodium cyanide, and indicates that the substance partitions in the water compartment rather than the lipid compartment.

Key value for chemical safety assessment

Log Kow (Log Pow):
-0.25

Additional information

Potassium cyanide and sodium cyanide can be considered as a chemical category, along with hydrogen cyanide (HCN) and acetone cyanohydrin (ACH, also known as 2-hydroxy-2-methylpropanenitrile), based on structural similarity, similar physico-chemical properties and common breakdown/metabolic products in physical and biological systems.
