beige to brown crystalline powder | [Uses]
8-Hydroxy-2-methylquinoline is used as pharmaceutical intermediate. | [Definition]
ChEBI: 2-Methylquinolin-8-ol is a hydroxyquinoline. | [Preparation]
8-hydroxyquinaldine is obtained from the reaction of 2-aminophenol with crotonaldehyde. Mix 2-aminophenol and 2-Nitrophenol homogeneously and add hydrochloric acid. Add crotonaldehyde under stirring. Heat for 6h and leave overnight. Distill the reacted o-nitrophenol by water distillation, and add sodium hydroxide solution to the residual solution to make it weakly basic. Then add powdered carbonyls for saturation, and distill 8-Hydroxyquinaldine by water distillation, and then distill the crude product under reduced pressure and recrystallize it with ethanol to obtain 8-hydroxyquinaldine. | [Synthesis Reference(s)]
Tetrahedron, 52, p. 2937, 1996 DOI: 10.1016/0040-4020(95)01118-8 | [General Description]
2-Methyl-8-quinolinol is a methyl substituted quinolinol derivative that shows fungicidal property. It can also undergo complexation with transition metal complexes. | [Purification Methods]
Crystallise the quinoline from EtOH or aqueous EtOH. Its solubility at 20o in H2O is 0.366g/L, and in CHCl3 it is 466g/L. It complexes with many metals. [Beilstein 21 H 106, 21 III/IV 2132.] |
