    • Chemical Class:

      A member of the class of thioureas that is thiourea in which one of the hydrogens is replaced by a phenyl group. Depending on their genetic makeup, humans find it either very bitter-tasting or tastele ss. This unusual property resulted in <element>N</element>-phenylthiourea being used in paternity testing prior to the advent of DNA testing. ChEBI CHEBI:46261
