التطبيق

Trimethylacetic anhydride is used as an acylation and esterification reagent, which participates in the acylation and esterification reactions with aniline and phenol. Trimethylacetic anhydride is also used in solid-phase oligonucleotide synthesis and kinetic separation of racemic 2-hydroxy – γ – butyrolactone and diphenylacetic acid, for the production of cyano-4, N-tert-butoxycarbonyl piperidine, and in solid-phase oligonucleotide synthesis.
