Phenylthiocarbamide (PTC), also known as phenylthiourea (PTU), is an organosulfur thiourea containing a phenyl ring. It has the unusual property that it either tastes very bitter or is virtually tasteless, depending on the genetic makeup of the taster. The ability to taste PTC is often treated as a dominant genetic trait, … See more The tested genetic taste phenomenon of PTC was discovered in 1931 when DuPont chemist Arthur Fox accidentally released a cloud of fine crystalline PTC.
