Common Name | 2-Methylpyridine |
---|
Description | 2-Methylpyridine, also known as alpha-picoline or 2-mepy, belongs to the class of organic compounds known as methylpyridines. These are organic compounds containing a pyridine ring substituted at one or more positions by a methyl group. 2-Methylpyridine, or 2-picoline, is the compound described with formula C6H7N. 2-Methylpyridine is a colorless liquid that has an unpleasant odor similar to pyridine. 2-Methylpyridine is a very strong basic compound (based on its pKa). 2-Methylpyridine is a bitter and sweat tasting compound. Outside of the human body, 2-Methylpyridine has been detected, but not quantified in, corns and tea. This could make 2-methylpyridine a potential biomarker for the consumption of these foods. Pyridines including 2-Methylpyridine are most crudely prepared by the reaction of acetylene and hydrogen cyanide. |
