Pyridine-3-carbaldehyde, also known as nicotinaldehyde, is an organic compound with the formula C 5 H 4 NCHO. It is one of three isomeric pyridinaldehydes. The other isomers are pyridine-2-carboxaldehyde and pyridine-4-carboxaldehyde. It is a colorless liquid that is routinely available commercially. It can be produced from nicotinonitrile ...
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]

Pyridine-borane (C 5 H 5 NBH 3, melting point 10–11 °C) is a mild reducing agent. structure of the Crabtree's catalyst. Transition metal pyridine complexes are numerous. [108] [109] Typical octahedral complexes have the stoichiometry MCl 2 (py) 4 and MCl 3 (py) 3. Octahedral homoleptic complexes of the type M(py) + 6 are rare or tend to ...
Pyridine-2-carbaldehyde, also called 2-formylpyridine, is an organic compound with the formula NC 5 H 4 CHO. It is one of three isomeric pyridinaldehydes. The other isomers are pyridine-3-carboxaldehyde and pyridine-4-carboxaldehyde.
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]
