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.
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 ...
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]
Isonicotinic acid or pyridine-4-carboxylic acid is an organic compound with the formula C 5 H 4 N(CO 2 H). It is a derivative of pyridine with a carboxylic acid substituent at the 4-position. It is an isomer of picolinic acid and nicotinic acid , which have the carboxyl group at the 2- and 3-position respectively compared to the 4-position for ...
The 5 substrates of this enzyme are 3-hydroxy-2-methylpyridine-5-carboxylate, NADH, NADPH, H +, and O 2, whereas its 3 products are 2-(acetamidomethylene)succinate, NAD +, and NADP +. This enzyme belongs to the family of oxidoreductases , specifically those acting on paired donors, with O 2 as oxidant and incorporation or reduction of oxygen.
