A pyridinecarboxylic acid is any member of a group of organic compounds which are monocarboxylic derivatives of pyridine. Pyridinecarboxylic acid comes in three isomers: Picolinic acid (2-pyridinecarboxylic acid) Nicotinic acid (3-pyridinecarboxylic acid), also known as Niacin; Isonicotinic acid (4-pyridinecarboxylic acid)
Picolinic acid is a bidentate chelating agent of elements such as chromium, zinc, manganese, copper, iron, and molybdenum in the human body. [5] [6] It is a substrate in the Mitsunobu reaction. In the Hammick reaction, picolinic acid reacts with ketones to give pyridine-2-carbonols: [7] NC 5 H 4 CO 2 H + R 2 C=O → NC 5 H 4 CR 2 (OH) + CO 2
Isonicotinic acid or pyridine-4-carboxylic acid is an organic compound with the formula C 5 H 4 N(CO 2 H). It is a derivative of pyridine with a carboxylic acid substituent at the 4-position. It is an isomer of picolinic acid and nicotinic acid, which have the carboxyl group at the 2- and 3-position respectively compared to the 4-position for ...
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 ...
The molecular formula C 6 H 5 NO 2 (molar mass: 123.11 g/mol, exact mass: 123.0320 u) may refer to: Nitrobenzene; Pyridinecarboxylic acid Isonicotinic acid; Nicotinic acid; Picolinic acid; 3-Hydroxyisonicotinaldehyde
