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) All isomers share the molecular weight 123,11 g/mol and the chemical formula C6H5NO2.

dbo:abstract
  • Die Pyridincarbonsäuren bilden in der Chemie eine Stoffgruppe von organischen Verbindungen, die zu den Heterocyclen (genauer: Heteroaromaten) zählt. Sie bestehen aus einem Pyridinring, der mit einer Carboxygruppe (–COOH) substituiert ist. Durch deren unterschiedliche Anordnung ergeben sich drei Konstitutionsisomere mit der Summenformel C6H5NO2. Sie sind vor allem unter ihren Trivialnamen Picolinsäure, Nicotinsäure und Isonicotinsäure bekannt. Sie lassen sich aus den Picolinen durch Oxidation der Methylgruppe z. B. mittels Kaliumpermanganat (KMnO4) darstellen. (de)

  • Os compostos orgânicos ácido piridinocarboxílico formam em Química uma família de compostos, pertencente aos compostos heterocíclicos (mais precisamente: heteroaromáticos). Consistem de um anel piridina, substituído com um grupo carboxila (−COOH). Através de arranjo diferente resultando em três isômeros constitucionais com a fórmula C6H5NO2. São mais conhecidos sob os nomes triviais ácido picolínico, ácido nicotínico e isonicotínico. Elas podem ser produzidos a partir das respectivas picolinas por oxidação do grupo metilo pelo permanganato de potássio (KMnO4). (pt)
