tropolonen.

Brit.

/ˈtrəʊpələʊn/, U.S.

/ˈtroʊpəˌloʊn/

Origin: Apparently formed within English, by derivation. Etymons: tropilidene n., -ol suffix, -one suffix.

Etymology: Apparently < trop- (in tropilidene n.) + -ol suffix + -one suffix.

Chemistry.

A crystalline ketone whose molecule contains a ring of seven carbon atoms and which is the parent of a series of compounds obtained from plants (as colchicine and the thujaplicins); (also) any substituted derivative of this.Systematic name: 2-hydroxytropone; C₇H₆O₂.
