Pyridinedicarboxylic acid

Pyridinedicarboxylic acid is a group of organic compounds which are dicarboxylic derivatives of pyridine. Pyridinedicarboxylic acid comes in several isomers:

• Quinolinic acid (2,3-pyridinedicarboxylic acid)
• Lutidinic acid (2,4-pyridinedicarboxylic acid)
• Isocinchomeronic acid (2,5-pyridinedicarboxylic acid)
• Dipicolinic acid (2,6-pyridinedicarboxylic acid)
• Cinchomeronic acid (3,4-pyridinedicarboxylic acid)
• Dinicotinic acid (3,5-pyridinedicarboxylic acid)

All isomers share the molecular weight 167.12 g/mol and the chemical formula C₇H₅NO₄.
