Uvitonic acid (6-methyl-2,4-pyridinedicarboxylic acid) is an organic compound with the formula CH 3 C 5 H 2 N(COOH) 2. The acid is a pyridine analogue of the benzene derivative uvitic acid . [ 1 ] Under normal conditions, the acid is a white crystalline substance.
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.
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.
One of the name reactions involving free radicals is the Minisci reaction. It can produce 2-tert-butylpyridine upon reacting pyridine with pivalic acid, silver nitrate and ammonium in sulfuric acid with a yield of 97%. [84]
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
When you buy a bottle of vitamins from a nutrition store, you’ll probably notice a best-by date on the bottom of the jar. But that inscribed number isn’t a hard-and-fast rule—there is some ...
A colorless solid, it is produced by ammoxidation of 3-methylpyridine: [2] H 3 CC 5 H 4 N + NH 3 + 1.5 O 2 → NCC 5 H 4 N + 3 H 2 O. Nicotinonitrile is a precursor to the vitamin niacin. [3] Nitrilase-catalyzed hydrolysis of 3-cyanopyridine by means of immobilized Rhodococcus rhodochrous J1 [2] strains leads in quantitative yield to ...
3-Methylpyridine degrades more slowly than the other two isomers, likely due to the impact of resonance in the heterocyclic ring. Like most simple pyridine derivatives, the picolines contain more nitrogen than is needed for growth of microorganisms, and excess nitrogen is generally excreted to the environment as ammonium during the degradation ...
