Quinaldine or 2-methylquinoline is a simple derivative of a heterocyclic compound quinoline.

Quinaldine has critical point at 787 K and 4.9 MPa and its refractive index is 1.8116.

It can be prepared from aniline and paraldehyde via Skraup synthesis or from aniline and crotonaldehyde via Doebner-von Miller variation of the Skraup reaction[1] or extracted from coal tar.

Uses

Quinaldine is used in anti-malaria drugs, in manufacturing dyes, food colorants (e.g. Quinoline Yellow WS), pharmaceuticals, pH indicators.

Quinaldine sulfate is an anaesthetic used in fish transportation.[2] In some Caribbean islands it is used to facilitate the collection of tropical fish from reefs.
