An aromatic ketone that is phloroglucinol in which two of the hydrogens attached to the benzene ring have been replaced by chlorines while the third has been replaced by a hexanoyl group. It is the immediate biosynthetic precursor for differentiation-inducing factor 1 (DIF-1). DIF-1 is released by developing Dictyostelium amoebae, inducing them to differentiate into stalk cells.
