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 an organic compound with the formula NC 5 H 4 CO 2 H. It is a derivative of pyridine with a carboxylic acid (COOH) substituent at the 2-position. It is an isomer of nicotinic acid and isonicotinic acid , which have the carboxyl side chain at the 3- and 4-positions, respectively.
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 ...
The reaction mechanism involves the acylation and activation of the acid 1 to the mixed anhydride 3. The amide will serve as a nucleophile for the cyclization forming the azlactone 4. Deprotonation and acylation of the azlactone forms the key carbon-carbon bond. Subsequent ring-opening of 6 and decarboxylation give the final keto-amide product ...
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
2-pyridinecarboxylic acid redirects to Picolinic acid. However, the article lists the molecular formula as C 6 H 5 NO 2, whereas ChemIDplus Advanced lists the molecular formula for 2-pyridinecarboxylic acid as C 13 H 11 NO 3, but also lists both Picolinic acid & Phenopicolinic acid as synonyms for 2-pyridinecarboxylic acid.
Aminopyralid is a selective herbicide used for control of broadleaf weeds, especially thistles and clovers. It is in the picolinic acid family of herbicides, which also includes clopyralid, picloram, triclopyr, and several less common herbicides.
