Sucrose octaacetate is an acetylated derivative of sucrose. It is used commercially and industrially in a variety of applications. It is used as an inert ingredient in pesticides and herbicides. As of December 2005 sucrose octaacetate was determined by the EPA to be completely nonharmful as an ingredient in pesticides.[2]

Sucrose octaacetate has been approved by the FDA as a food additive. It has a bitter taste which has led to its use as bitterant and an aversive agent. The chemical has also been used to determine tasters from non-tasters in mice.[3]
