General description
Potassium nitrate is a water-soluble inorganic salt that is commonly used as nitrogen fertilizer. It is also found in toothpastes as a desensitizer for tooth hypersensitivity. The addition of KNO3 to growth medium has shown to promote growth in salt stressed melon plants.
Application
Potassium nitrate may be used in the synthesis of 5-bromo-8-nitroisoquinoline via bromination of isoquinoline using N-bromosuccinimide.
