About

Picolinic Acid is an organic compound. It is a derivative of pyridine with a carboxylic acid substituent at the 2-position. It is an isomer of nicotinic acid, which has the carboxyl side chain at the 3-position. It is a white solid that is soluble in water. In synthetic organic chemistry, has been used as a substrate in the Mitsunobu reaction and in the Hammick reaction.

Picolinic Acid is a bidentate chelating agent of elements such as chromium, zinc, manganese, copper, iron, and molybdenum in the human body.
