Storage method

This product should be sealed and stored in a cool, dry place away from light.

Synthesis method

N-benzoyl-2-hydrogen-2-cyanoquinoline is obtained by reacting benzoyl chloride and potassium cyanide quinoline in water, and then hydrolyzed to obtain quinalcolic acid.

Purpose

Precipitant, used to test copper and determine copper, iron, zinc and uranium (can form insoluble salts with these metals).
