Pyridine-4-carbaldehyde

http://dbpedia.org/resource/Pyridine-4-carbaldehyde an entity of type: Thing

4-Pyridincarbaldehyd (Trivialname Isonicotinaldehyd) ist eine chemische Verbindung, die sich von der Isonicotinsäure ableitet. Es handelt sich um ein Pyridin-Derivat. rdf:langString
Pyridine-4-carbaldehyde is an organic compound with the formula C5H4NCHO. 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. It condenses with pyrrole to give tetrapyridylporphyrin. The pKa has been experimentally determined by NMR spectroscopy to be 4.72. rdf:langString
吡啶-4-甲醛是一种有机化合物，化学式为C5H4NCHO，是吡啶甲醛的同分异构体之一。它是无色液体，久置后会变为黄色或棕色。它可以发生芳香醛的反应，如还原胺化和生成席夫碱。它可以和吡咯缩合，得到四吡啶基卟啉。 rdf:langString
