Trimethylacetic anhydride CAS 1538-75-6
ʻO Trimethylacetic anhydride ka papa o nā pūhui alkyl anhydride, hiki ke hoʻomākaukau ʻia e ka hopena dehydration o ka waika valeric. He kiʻekiʻe kiʻekiʻe ka hana kemika a hoʻohana mau ʻia ma ke ʻano he acylation reagent ma ke kahua o ka kemika synthesis organik. Hiki ke hoʻohana ʻia no ka esterification reactions o nā waiʻona a me nā pūhui phenolic

Hoʻohana ʻia ʻo Trimethylacetic anhydride e like me ka acylation a me ka esterification reagent, e komo ana i ka acylation a me ka esterification reactions me aniline a me phenol. Hoʻohana pū ʻia ʻo Trimethylacetic anhydride i ka synthesis oligonucleotide solid-phase a me ka hoʻokaʻawale kinetic o racemic 2-hydroxy - γ - butyrolactone a me ka waikawa diphenylacetic, no ka hana ʻana o cyano-4, N-tert-butoxycarbonyl piperidine, a me ka solid-phase synthesis oligonucleotide.
Hoʻopili pinepine ʻia i ka 25kg / pahu, a hiki ke hana ʻia i ka pōʻai maʻamau.
