6-Methylquinoline Structural

What is 6-Methylquinoline?

Chemical properties

6-Methylquinoline is a clear light yellow to light orange liquid that has a pungent, heavy odor. dissolved in 4 volumes of 50% ethanol or 60% ethanol of the same volume and in oily fragrances. May be synthesized from p-amino-benzaldehyde and acetone.

Occurrence

Reported found in Finnish and Japanese whiskey.

The Uses of 6-Methylquinoline

6-Methylquinoline can be used as primary carbon source in culture of Pseudomonas putida QP1. 6-Methylquinoline was used in the synthesis of fluorescent halide-sensitive quinolinium dyes and fluorescent probes for determination of chloride in biological systems.

What are the applications of Application

6-Methylquinoline, is a building block used for the synthesis of various pharmaceutical compounds, and biologically active compounds. It can be used for the preparation of pyranobenzopyrone compounds, having anti-norovirus activity.

Definition

ChEBI: 6-methylquinoline is a member of quinolines.

General Description

Clear pale yellow liquid or oil with a quinoline odor.

Air & Water Reactions

Insoluble in water.

Reactivity Profile

6-Methylquinoline is sensitive to prolonged exposure to light. May react vigorously with strong oxidizing agents and strong acids . Neutralizes acids in exothermic reactions to form salts plus water. May be incompatible with isocyanates, halogenated organics, peroxides, phenols (acidic), epoxides, anhydrides, and acid halides. Flammable gaseous hydrogen may be generated in combination with strong reducing agents, such as hydrides.

Fire Hazard

6-Methylquinoline is probably combustible.

Biochem/physiol Actions

6-Methylquinoline undergoes biodegradation by quinoline-degrading culture of Pseudomonas putida.

Synthesis

6-Methylquinoline is obtain from coal tar, by synthesis from p-aminobenzaldehyde and acetone.

Purification Methods

Reflux it with BaO, then fractionally distil it. Further purified it via its recrystallised ZnCl2 complex (m 190o). [Cumper et al. J Chem Soc 1176 1962, Beilstein 20 III/IV 3498, 20/7 V 400.]
