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.
The systematic name of this enzyme class is 2-amino-3-(3-oxoprop-1-en-1-yl)but-2-enedioate carboxy-lyase (2-aminomuconate-semialdehyde-forming). Other names in common use include picolinic acid carboxylase, picolinic acid decarboxylase, alpha-amino-beta-carboxymuconate-epsilon-semialdehade decarboxylase, alpha-amino-beta-carboxymuconate-epsilon-semialdehyde, beta-decarboxylase, 2-amino-3-(3 ...

Evidence that the Cr 3+ center coordinates to the pyridine nitrogen comes from a shift in the IR spectra of a C=N vibration at 1602.4 cm −1 for free picolinic acid to 1565.9 cm −1 for chromium(III) picolinate. [11] The bond length between Cr 3+ and the nitrogen atom of the pyridine ring on picolinate ranges from 2.047 to 2.048 Å. [12]
He recognized the acid from β–picoline as Nicotinsäure (nicotinic acid or "niacin"), [12] which Weidel had discovered in 1873. [13] When Weidel decarboxylated the carboxylic acid of each isomer – by dry distilling its calcium salt with calcium oxide – the reaction yielded pyridine, thus showing that picoline was a mixture of three ...
Clopyralid (3,6-dichloro-2-pyridinecarboxylic acid) is a selective herbicide used for control of broadleaf weeds, especially thistles and clovers.Clopyralid is in the picolinic acid family of herbicides, which also includes aminopyralid, picloram, triclopyr, and several less common herbicides.
It is in the picolinic acid family of herbicides, which also includes clopyralid, picloram, triclopyr, and several less common herbicides. [ 2 ] [ 3 ] It was first registered for use in 2005, in the USA under the brand name "Milestone" [ 4 ] and later under various names starting with "Grazon". [ 5 ]
2-Methylpyridine, or 2-picoline, is the compound described with formula C 6 H 7 N. 2-Picoline is a colorless liquid that has an unpleasant odor similar to pyridine. It is mainly used to make vinylpyridine and the agrichemical nitrapyrin .
