| Common Name | 3-Methylpyridine |
|---|
| Description | 3-Methylpyridine, also known as beta-picoline or 3-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. 3-Methylpyridine is a very strong basic compound (based on its pKa). A methylpyridine that is pyridine substituted by a methyl group at position 3. Outside of the human body, 3-Methylpyridine has been detected, but not quantified in, sweet oranges and tea. This could make 3-methylpyridine a potential biomarker for the consumption of these foods. |
