[C][=C][C][=C][Branch1][Branch1][C][=C][Ring1][=Branch1][N][C][=Branch1][C][=S][N]"}, {"from": "gpt", "value": "The molecule is 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 tasteless. This unusual property resulted in N-phenylthiourea being used in paternity testing prior to the advent of DNA testing. It has a role as an EC 1.14.18.1 (tyrosinase) inhibitor. It is functionally related to a thiourea."}]
