Common NameN-Ethylpropionamide
DescriptionN-ethylpropionamide is a member of the class of compounds known as secondary carboxylic acid amides. Secondary carboxylic acid amides are compounds containing a secondary carboxylic acid amide functional group, with the general structure RC(=O)N(R')H (R,R'=alkyl, aryl). N-ethylpropionamide is soluble (in water) and a very weakly acidic compound (based on its pKa). N-ethylpropionamide can be found in tea, which makes N-ethylpropionamide a potential biomarker for the consumption of this food product.
