  <name>2-Acetyl-4-methylthiazole</name>
  <description>2-acetyl-4-methylthiazole is a member of the class of compounds known as aryl alkyl ketones. Aryl alkyl ketones are ketones have the generic structure RC(=O)R', where R = aryl group and R'=alkyl group. 2-acetyl-4-methylthiazole is slightly soluble (in water) and a very weakly acidic compound (based on its pKa). 2-acetyl-4-methylthiazole can be found in kohlrabi, which makes 2-acetyl-4-methylthiazole a potential biomarker for the consumption of this food product. </description>
