3-Aminopyridine Usage And Synthesis

Chemical Properties

white to light yellow crystal powder

Uses

3-Aminopyridine is a monosubstituted pyridine that shows convulsive effects on cortical Neurons. 3-Aminopyridine is used in the synthesis of of organic ligand 3-Pyridylnicotinamide. 3-Aminopyridine al ong with other aminopyridines have been shown to reversibly block voltage-dependent potassium channels,

Uses

3-Aminopyrodine is also used as an intermediate for agrochemicals, pharmaceuticals and colorants. These are involved in photosensitizer chemistry, luminescent materials, metal complex chemistry and liquid crystal. Aminopyridine is used as a monomer for polymerization. It is also used in the Production of cationic dyes and Apa amoxicillin sodium raw materials.

Uses

manufacture of pharmaceuticals and dyes.
