3-Methylpyridine or 3-picoline, is an organic compound with formula 3-CH 3 C 5 H 4 N. It is one of three positional isomers of methylpyridine , whose structures vary according to where the methyl group is attached around the pyridine ring.
The structure of niacin, and thus β–picoline, was determined in 1883 when the Czech-Austrian chemist Zdenko Hans Skraup and Albert Cobenzl repeatedly oxidized β–naphthoquinoline and found niacin among the products, thus proving that β–picoline was 3-methylpyridine. [16]
Structure of Zn(picolinate) 2 (H 2 O) 2. Hydrogenation of picolinic acid gives piperidine-2-carboxylic acid, a precursor to the drug Mepivacaine. 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.

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 ...
In 2018, Mendenhall went on to be convicted of the murder of Symantha Winters, whose body was found inside a trash can at a truck stop in Lebanon, Tennessee, on June 6, 2007. The case resulted in ...
5-Ethyl-2-methylpyridine is an organic compound with the formula (C 2 H 5)(CH 3)C 5 H 3 N. One of several isomeric pyridines with this formula, this derivative is of interest because it is efficiently prepared from simple reagents and it is a convenient precursor to nicotinic acid, a form of vitamin B 3. 5-Ethyl-2-methylpyridine is a colorless ...
