Pivalic Acid is a metabolite of oral cephem (β-lactam) antibiotics
such as S-1108, containing pivaloyl moieties.
Pivalic acid is a carboxylic acid. Carboxylic acids donate hydrogen
ions if a base is present to accept them. They react in this way
with all bases, both organic (for example, the amines) and
inorganic. Their reactions with bases, called "neutralizations",
are accompanied by the evolution of substantial amounts of heat.
Neutralization between an acid and a base produces water plus a
salt. Carboxylic acids with six or fewer carbon atoms are freely or
moderately soluble in water; those with more than six carbons are
slightly soluble in water. Soluble carboxylic acid dissociate to an
extent in water to yield hydrogen ions. The pH of solutions of
carboxylic acids is therefore less than 7.0.
Pivalic acid is a carboxylic acid with a molecular formula of
(CH3)3CCO2H. This colourless, odiferous organic compound is solid
at room temperature.
