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.
2-Methylpyridine, or 2-picoline, is the compound described with formula C 6 H 7 N. 2-Picoline is a colorless liquid that has an unpleasant odor similar to pyridine. It is mainly used to make vinylpyridine and the agrichemical nitrapyrin .
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
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.
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).
Congress is gathering for a joint session to certify the results of the 2024 election, the final step before President-elect Donald Trump's inauguration on Jan. 20, after some major changes to ...
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 ...
