Trimethylacetic acid can be used as an internal chemical-shift standard for NMR of aqueous solutions. It is a metabolite of oral cephem (β-lactam) antibiotics such as S-1108, containing pivaloyl moieties.

In the presence of an Ag(II) species (from silver nitrate and ammonium persulfate in TFA), tert-butyl radicals are generated. With quinoline, the 2-tert-butyl substituted derivative is formed in high yield: Tetrahedron, 46, 2525 (1990), whereas for most other carboxylic acids, both 2- and 4-substitution usually occur.
