Pyridine-2-carbaldehyde, also called 2-formylpyridine, is an organic compound with the formula NC 5 H 4 CHO. It is one of three isomeric pyridinaldehydes. The other isomers are pyridine-3-carboxaldehyde and pyridine-4-carboxaldehyde. Pyridine-2-carbaldehyde is a colorless oily liquid with a distinctive odor.
Pralidoxime (2-pyridine aldoxime methyl chloride) or 2-PAM, usually as the chloride or iodide salts, belongs to a family of compounds called oximes that bind to organophosphate-inactivated acetylcholinesterase. [1] It is used to treat organophosphate poisoning [2] in conjunction with atropine and either diazepam or midazolam. It is a white solid.
2-Methyl-6-(phenylethynyl)pyridine (MPEP) is a research drug which was one of the first compounds found to act as a selective antagonist for the metabotropic glutamate receptor subtype mGluR5. After being originally patented as a liquid crystal for LCDs, it was developed by the pharmaceutical company Novartis in the late 1990s. [ 1 ]
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. Alternatively, it arises by the aerobic oxidation of the corresponding alcohol. [1]
For comparison, crystalline benzene is also orthorhombic, with space group Pbca, a = 729.2 pm, b = 947.1 pm, c = 674.2 pm (at 78 K), but the number of molecules per cell is only 4. [18] This difference is partly related to the lower symmetry of the individual pyridine molecule (C 2v vs D 6h for benzene).
98-98-6 59-67-6 55-22-1 All isomers share the molecular weight 123,11 g/mol and the chemical formula C 6 H 5 NO 2. See also. Pyridinedicarboxylic acid
In 1871, the English chemist and physicist James Dewar speculated that picoline was methylpyridine. [8] If the structure of pyridine that had been proposed in 1869 by the German-Italian chemist Wilhelm Körner were correct, that is, if pyridine were analogous to benzene (a hexagonal ring of alternating single and double bonds), [ 9 ] then there ...
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 ...
