Sucrose octaacetate

蔗糖八乙酸酯,

Sucrose octaacetate is used commercially and industrially in a variety of applications including as an inert ingredient in pesticides and herbicides and has been approved by the EPA as an inert ingredient in pesticides due to its low toxicity. It has also been approved by the FDA as a food additive. It has a bitter taste and is used as a bitterant to deter accidental ingestion.

Sucrose octaacetate, also known as octaacetyl sucrose or fema 3038, belongs to the class of organic compounds known as o-glycosyl compounds. These are glycoside in which a sugar group is bonded through one carbon to another group via a O-glycosidic bond. Sucrose octaacetate exists as a solid and is considered to be practically insoluble (in water) and relatively neutral. Within the cell, sucrose octaacetate is primarily located in the cytoplasm. Sucrose octaacetate has a bitter and odorless taste.
