  <name>Benzyl ethyl ketone</name>
  <description>Benzyl ethyl ketone, also known as 1-phenyl-2-butanone, belongs to benzene and substituted derivatives class of compounds. Those are aromatic compounds containing one monocyclic ring system consisting of benzene. Benzyl ethyl ketone is practically insoluble (in water) and an extremely weak acidic compound (based on its pKa). Benzyl ethyl ketone can be found in tea, which makes benzyl ethyl ketone a potential biomarker for the consumption of this food product. </description>
