Trimethylacetic anhydride is used as acylation and esterification reagents. It is involved in acylation and esterification reactions with anilines and phenols. It is also used in solid-phase oligonucleotide synthesis and in the kinetic resolution of racemic 2-hydroxy-gamma-butyrolactones with diphenylacetic acid. It is also employed in the production of cyano-4, N-tert-butyloxycarbonyl piperidine.

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.
