Application

6-Chloropyridine-3-carboxylic acid (6-chloronicotinic acid/6-CNA) has been used to study its photolytic and photocatalytic degradation. 6-CNA is a degradation product of neonicotinoid insecticides imidacloprid and acetamiprid and is known to appear in different environmental matrices. The product has been used as a media component during the isolation of 6-CNA degrading bacterial strain from imidacloprid-exposed soil samples.

The determination of imidacloprid and its main metabolite (6-chloronicotinic acid) in honeybees was performed by liquid chromatography with post-column photochemical derivatisation in alkaline medium and fluorescence detection. The compounds were extracted from honeybees with acetone under ultrasound conditions prior to
