Trimethylacetic anhydride CAS 1538-75-6 ni iki?

Anhydride ya Trimethylacetic iri mu bwoko bw'ibinyabutabire bya alkyl anhydride, bishobora gutegurwa hakoreshejwe uburyo bwo gukura amazi mu mubiri bwa aside valeric. Ifite ubushobozi bwo gukora ibinyabutabire bwinshi cyane kandi ikunze gukoreshwa nk'uburyo bwo gukora acylation mu bijyanye na shimi ya organic synthesis. Ishobora gukoreshwa mu gukora esterification y'ibinyabutabire bya alcool na phenolic.

Porogaramu

Anhydride ya Trimethylacetic ikoreshwa nk'igikoresho cyo gukaraba no gukaraba, kigira uruhare mu gukora acylation no gukaraba hamwe na aniline na phenol. Anhydride ya Trimethylacetic ikoreshwa kandi mu gukora oligonucleotide ikora mu buryo bwa solid-phase no mu gutandukanya kinetic ya racemic 2-hydroxy - γ - butyrolactone na diphenylacetic acid, mu gukora cyano-4, N-tert-butoxycarbonyl piperidine, no mu gukora oligonucleotide ikora mu buryo bwa solid-phase.
