Quinaldic acid is an organic chemical compound.

Quinaldic acid can form a zwitterion, where a proton is transferred from the carboxylic acid group to the nitrogen atom. Neptunium and uranium can form mixed ligand compounds with quinaldic acid.

Quinaldic acid has been used in the gravimetric analysis of uranium in the form of uranyl ion. This is precipitated by forming an insoluble salt with quinaldic acid. When incinerated U₃O₈ is formed and can be weighed.
