|Section2= |Section3= }} Picolinic acid is an organic compound with the formula C5H4N(CO2H). 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 ) chapter in Philip L. Fuchs. Handbook of Reagents for Organic Synthesis: Catalytic Oxidation Reagents. John Wiley & Sons, Jul 29, 2013 ISBN 9781118704820〕 ==Coordination chemistry== Picolinic acid is a bidentate chelating agent of elements such as chromium, zinc, manganese, copper, iron, and molybdenum in the human body.〔 Many of its complexes are charge-neutral and thus lipophilic. After its role in absorption was discovered, zinc dipicolinate dietary supplements became popular as they were shown to be an effective means of introducing zinc into the body.〔 抄文引用元・出典: フリー百科事典『 ウィキペディア（Wikipedia）』 ■ウィキペディアで「Picolinic acid」の詳細全文を読む スポンサード リンク
