Description

Other Notes

Reagent for the decomposition of cassiterite by fusion

A -D suffix exists for administrative purposes only.
All -D packages are 100% the same product, same quality, same specification as the package sizes previously sold without a -D.

Application

Sodium cyanide may be employed for the synthesis of the following compounds:
• α-amino acids
• Prussian blue (cyanide pigment)
• nitriles, via reaction with primary and secondary chlorides

General description

Sodium cyanide is colorless sodium salt and its crystals belong to the cubic crystal system. Its aqueous solutions are strongly basic due to the presence of cyanide ion. It can be synthesized by reacting sodium hydroxide with hydrogen cyanide. It is a key precursor for the synthesis of various organic intermediates. It participates in the RuCl3-mediated oxidative cyanation of tertiary amines.
