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
3-Picoline is a useful precursor to agrochemicals, such as chlorpyrifos. [1] Chlorpyrifos is produced from 3,5,6-trichloro-2-pyridinol, which is generated from 3-picoline by way of cyanopyridine. This conversion involves the ammoxidation of 3-methylpyridine: CH 3 C 5 H 4 N + 1.5 O 2 + NH 3 → NCC 5 H 4 N + 3 H 2 O
By 1879, the Austrian chemist Hugo Weidel had succeeded in isolating and characterizing three isomers of picoline, which he denoted α–, β–, and γ–picoline: [10] α–picoline was the main component of impure picoline; it was accompanied by small quantities of β–picoline; and γ–picoline was produced by Baeyer's dry distillation of ...

Chromium(III) picolinate (also trivalent chromium) is a chemical compound with the formula Cr(C 5 H 4 N(CO 2)) 3, commonly abbreviated as CrPic 3. It is a bright-red coordination compound derived from chromium(III) and picolinic acid.

2-Picoline was the first pyridine compound reported to be isolated in pure form. It was isolated from coal tar in 1846 by T. Anderson. [2] This chemistry was practiced by Reilly Industries. [3] It is now mainly produced by two principal routes. One method involves the condensation of acetaldehyde and ammonia in the presence of an oxide catalyst ...
