Use：: Relative to esters of most carboxylic acids, esters of pivalic acid are unusually resistant to hydrolysis. Some applications result from this thermal stability. Polymers derived from pivalate esters of vinyl alcohol are highly reflective lacquers. The pivaloyl (abbreviated Piv or Pv) group is a protective group for alcohols in organic synthesis. Pivalic acid is sometimes used as an internal chemical shift standard for NMR spectra of aqueous solutions. While DSS is more commonly used for this purpose, the minor peaks from protons on the three methylene bridges in DSS can be problematic. The 1H NMR spectrum at 25 °C and neutral pH is a singlet at 1.08 ppm. Pivalic acid is employed as co-catalyst in some of the Palladium catalyzed C-H functionalization reaction.
