4-Quinolinecarboxaldehyde Usage And Synthesis

Chemical Properties

yellow to yellow-brown crystalline powder

Occurrence

The common presence of 4-quinolinecarboxaldehyde in honey from Galicia (northwest of Spain). As opposed to other quinoline carboxylic acid derivatives, the 4- quinolinecarboxaldehyde species has not been correlated with the anti-diabetic properties of honey; nevertheless, it appears to be active against intestinal bacteria.

Uses

4-Quinolinecarboxaldehyde was used in the synthesis of lepidylamines. It also shows antimicrobial activity toward human intestinal bacteria such as Clostridium perfringens.
