Hexaethyl tetraphosphate (also known as HETP) is the organophosphorus compound with the chemical formula [(C₂H₅O)₃P₂O₃]₂O. The compound has not been isolated in pure form but appears to be a colorless liquid at room temperature. Commercial samples appear brown due to impurities.^[1]^[2] It is a constituent of the insecticide Bladan.^[3] In the 1940s, it was about as significant an insecticide as DDT and was referred to as "another of DDT's rivals for fame" in a 1948 book.^[4]
