6-Chloronicotinic acid Usage And Synthesis

Chemical Properties

Off-white to beige crystalline powder

Uses

6-Chloronicotinic acid is used as building block for different chemical synthesis. It is an intermediate for the synthesis of N-(thiophen-2-yl) benzamide derivatives as BRAFV600E inhibitors, and novel DNA-gyrase B inhibitors.

Uses

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.

Definition

ChEBI: 6-Chloronicotinic acid is a member of pyridines and an aromatic carboxylic acid.

General Description

6-Chloropyridine-3-carboxylic acid is a metabolite of the neonicotinoid pesticides, imidacloprid and acetamiprid and occurs in different environmental matrices.(3) It is widely used in agricultural crop protection, domestic insect control and environmental pest management.

Purification Methods

Purify it by recrystallisation from hot H2O and sublime it in a vacuum. [Pechmann & Welsch Chem Ber 17 2384 1884, Herz & Murty J Org Chem 26 122 1961, Beilstein 22/2 V 177.]
