Isobenzan (telodrin) is a highly toxic organochloride insecticide. It was produced only in the period from 1958 to 1965 and its use has been since discontinued.^[1] It is a persistent organic pollutant that can remain in soil for 2 to 7 years, and the biological half-life of isobenzan in human blood is estimated to be about 2.8 years.^[1]
