• The bitterness of the compound guides most applications of denatonium. Denatonium benzoate is used to denature ethanol so that it is not treated as an alcoholic beverage with respect to taxation and sales restrictions.

• Denatonium is commonly included in placebos used in clinical trials to mimic the bitter taste of certain medications.

• Denatonium also discourages consumption of poisonous alcohols such as methanol and additives such as ethylene glycol.

• It is also added to many kinds of harmful liquids including solvents (such as nail polish remover), paints, varnishes, toiletries and other personal care items, special nail polish for preventing nail biting, and various other household products. It is also added to less hazardous aerosol products (such as gas dusters) to discourage inhalant abuse of the volatile vapors.

• Animals are known to have different sensitivities to the effects of denatonium. It is used in some animal repellents (especially for such large mammals as deer). It has been used to safeguard rat poisons from human consumption, as humans are able to detect denatonium at much lower concentrations than rodents.
