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.
This page contains tables of azeotrope data for various binary and ternary mixtures of solvents. The data include the composition of a mixture by weight (in binary azeotropes, when only one fraction is given, it is the fraction of the second component), the boiling point (b.p.) of a component, the boiling point of a mixture, and the specific gravity of the mixture.
Picoline refers to any of three isomers of methyl pyridine (CH 3 C 5 H 4 N). They are all colorless liquids with a characteristic smell similar to that of pyridine. They are miscible with water and most organic solvents.

4-Methylpyridine is the organic compound with the formula CH 3 C 5 H 4 N. It is one of the three isomers of methylpyridine. This pungent liquid is a building block for the synthesis of other heterocyclic compounds. Its conjugate acid, the 4-methylpyridinium ion, has a pK a of 5.98, about 0.7 units above that of pyridine itself. [1]
Pyridine-3-carbaldehyde, also known as nicotinaldehyde, is an organic compound with the formula C 5 H 4 NCHO. It is one of three isomeric pyridinaldehydes. The other isomers are pyridine-2-carboxaldehyde and pyridine-4-carboxaldehyde. It is a colorless liquid that is routinely available commercially. It can be produced from nicotinonitrile ...
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 ...
(Mesitylene)molybdenum tricarbonyl arises from the reaction of molybdenum hexacarbonyl with hot mesitylene: [1]. Mo(CO) 6 + (CH 3) 3 C 6 H 3 → Mo(CO) 3 [(CH 3) 3 C 6 H 3] + 3 CO It can also be synthesized, with good yields by displacement of pyridine ligands of the trispyridine complex Mo(CO) 3 (pyridine) 3 in the presence of Lewis acids.
