The molecule is a butenolide that is but-2-en-4-olide bearing a 2,4,6-trimethylphenyl group at position 3, a 3,3-dimethylbutyryloxy group at position 4 and a spiro-fused cyclopentyl ring at position 5. It has a role as an insecticide. It derives from a 1,3,5-trimethylbenzene and a 3,3-dimethylbutyric acid.
