2-Aminopyridine is an organic compound with the formula H2NC5H4N.

It is a colourless solid that is used in the production of the drugs piroxicam, sulfapyridine, tenoxicam, and tripelennamine.

It is produced by the reaction of sodium amide with pyridine, the Chichibabin reaction.

[3] Although 2-hydroxypyridine converts significantly to the pyridone tautomer, the related imine tautomer (HNC5H4NH) is less important for 2-aminopyridine.

The acute toxicity is indicated by the LD50 = 200 mg/kg (rat, oral).
