Chemical Information
FooDB Name2-Methylpyridine
Description2-methylpyridine, also known as 2-picoline or 2-mepy, is a member of the class of compounds known as methylpyridines. Methylpyridines are organic compounds containing a pyridine ring substituted at one or more positions by a methyl group. 2-methylpyridine is soluble (in water) and a very strong basic compound (based on its pKa). 2-methylpyridine is a bitter and sweat tasting compound found in tea, which makes 2-methylpyridine a potential biomarker for the consumption of this food product. 2-methylpyridine can be found primarily in saliva. 2-methylpyridine exists in all eukaryotes, ranging from yeast to humans. 2-Methylpyridine, or 2-picoline, is the compound described with formula C6H7N. 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 .
