3-Hydroxyisonicotinaldehyde (HINA), also known as 3-hydroxypyridine-4-carboxaldehyde, is a derivative of pyridine, with hydroxyl and aldehyde substituents. It has been studied as a simple analogue of vitamin B 6. In 2020, it was reported as having the lowest molecular weight of all dyes which exhibit green fluorescence. [2] [3]
It is one of three isomeric pyridinaldehydes. The other isomers are pyridine-2-carboxaldehyde and pyridine-3-carboxaldehyde. Pyridine-4-carboxaldehyde is a colorless liquid, although aged samples can appear yellow or even brown. It undergoes many reactions expected for aromatic aldehydes such as reductive amination and Schiff base formation. [1]
