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.
This Thermo Scientific Chemicals brand product was originally part of the Alfa Aesar product portfolio. Some documentation and label information may refer to the legacy brand. The original Alfa Aesar product / item code or SKU reference has not changed as a part of the brand transition to Thermo Scientific Chemicals.
Applications
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.
Solubility
Soluble in alcohol, ether. Slightly soluble in water
Notes
Stable under recommended storage conditions. Incompatible with oxidizing agents and bases.

- 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.
