Trityl
WebThe triphenylmethyl radical (often shorted to trityl radical) is an organic compound with the formula (C 6 H 5) 3 C. It is a persistent radical. It was the first radical ever to be described in organic chemistry. Because of its accessibility, the trityl radical has been heavily exploited. Protecting group The triphenylmethyl substituent, also called trityl, is widely used in organic chemistry.
