Denatonium ethanol has been denatured using denatonium benzoate. The common name for this chemical, "denat"onium, alludes to this application. Denatonium is commonly included in placebo medications used in clinical trials to match the bitter taste of certain medications. Denatonium also discourages consumption of harmful alcohols like methanol, and additives like ethylene glycol. Denatonium is used in rubbing alcohol as an inactive ingredient. 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.

Nitroethane give an oxazoline, which protonates to give a cationic surfactant. Like some other nitrated organic compounds, nitroethane is also used as a fuel additive and a precursor to explosives. Nitroethane is a useful solvent for polymers such as polystyrene and is particularly useful for dissolving cyanoacrylate adhesives. In niche applications, it has been used as a component in artificial nail remover and in overhead ceiling sealant sprays. Nitroethane has been used as a chemical feedstock in clandestine laboratories for synthesis of controlled substances such as amphetamines. Nitroethane is suspected to cause genetic damage and be harmful to the nervous system.
