General description

Methyl pivalate is a methyl ester derived from pivalic acid and methanol. It finds use as a solvent and an agent for transesterification reactions. It has gained attention for its positive environmental attributes. It exhibits a significantly lower ozone-forming potential compared to widely used oxygenated solvents like n-butyl ethanoate and butanol, as measured by a maximum incremental reactivity scale.

Application

Methyl pivalate can be used as a solvent for preparing the ISTD solution, diluting allergen standards, and aiding in the extraction of the sample components during the GC-MS analysis process.
