ʻO ka anhydride Trimethylacetic CAS 1538-75-6
No ka papa o nā hui alkyl anhydride ka Trimethylacetic anhydride, hiki ke hoʻomākaukau ʻia ma o ka hopena dehydration o ka valeric acid. Loaʻa iā ia ka reactivity kemika kiʻekiʻe loa a hoʻohana pinepine ʻia ma ke ʻano he acylation reagent ma ke kahua o ka kemika synthesis organic. Hiki ke hoʻohana ʻia no nā hopena esterification o nā alcohols a me nā hui phenolic.

Hoʻohana ʻia ʻo Trimethylacetic anhydride ma ke ʻano he acylation a me ka esterification reagent, kahi e komo ai i nā hopena acylation a me ka esterification me ka aniline a me ka phenol. Hoʻohana pū ʻia ʻo Trimethylacetic anhydride i ka synthesis oligonucleotide phase solid a me ka hoʻokaʻawale kinetic o ka racemic 2-hydroxy - γ - butyrolactone a me ka diphenylacetic acid, no ka hana ʻana o cyano-4, N-tert-butoxycarbonyl piperidine, a ma ka synthesis oligonucleotide phase solid.
Hoʻopili pinepine ʻia i loko o 25kg / pahu, a hiki ke hana ʻia kahi pūʻolo i hoʻopilikino ʻia.
