Chemische Eigenschaften
Denatonium benzoate occurs as an odorless, very bitter tasting, white crystalline powder or granules.
Verwenden
Pharmaceutic aid (alcohol denaturant); pharmaceutic aid (flavor).
Vorbereitung Methode
Denatonium benzoate was first synthesized in the 1950s and is usually prepared by reacting denatonium chloride with benzyl benzoate.
Pharmazeutische Anwendungen
Denatonium benzoate is among the most bitter of substances
known and is detectable at concentrations of approximately 10 ppb.
In pharmaceutical and other industrial applications it is added to
some products as a deterrent to accidental ingestion. It is most
commonly used at levels of 5–500 ppm. Denatonium benzoate may
also be used to replace brucine or quassin as a denaturant for
ethanol.
In pharmaceutical formulations, denatonium benzoate has been
used as a flavoring agent in placebo tablets, and in a topical
formulation it has been used in an anti-nailbiting preparation.

LD50 (rabbit, oral): 0.508g/kg
LD50 (rat, oral): 0.584g/kg
Lager
Denatonium benzoate is stable up to 140°C and over a wide pH range. It should be stored in a well-closed container (such as polythene-lined steel) in a cool, dry place. Aqueous or alcoholic solutions retaintheir bitterness forseveral years evenwhenexposed to light.
Inkompatibilitäten
Denatonium benzoateis incompatible with strongoxidizing agents.
