ʻO Trifluoromethanesulfonic anhydride, i ʻike ʻia hoʻi he triflic anhydride, ʻo ia ka hui kemika me ka formula₂O.
ʻO ia ka waikawa anhydride i loaʻa mai ka triflic acid.
He electrophile ikaika kēia pūhui, pono no ka hoʻokomo ʻana i ka hui triflyl, CF₃SO₂.
Hoʻopau ʻia ʻo Tf₂O, triflic anhydride ka acid anhydride o ka waikawa triflic acid ikaika, CF₃SO₂OH.

ʻO Trifluoromethanesulfonic Anhydride kahi electrophile ikaika i hoʻohana ʻia i ka synthesis kemika no ka hoʻokomo ʻana i ka hui triflyl.
Hoʻohana ʻia ka trifluoromethanesulfonic anhydride e hoʻohuli i nā phenols a me ka imine i loko o ka triflic ester a me ka hui NTf. He electrophile ikaika ia i hoʻohana ʻia no ka hoʻokomo ʻana i ka hui triflyl i ka synthesis kemika. Hoʻohana ia ma ke ʻano he reagent i ka hoʻomākaukau ʻana i nā alkyl a me vinyl triflates, a no ka stereoselective synthesis o mannosazide methyl uronate donors. Hana ia ma ke ʻano he catalyst no ka glycosylation me ka anomeric hydroxy sugars e hoʻomākaukau ai i nā polysaccharides.
ʻO ka lawelawe hiki iā mākou ke hāʻawi
1) Hiki ke hoʻopaʻa inoa ʻia ka ʻaelike maʻamau
2) Hiki ke pūlima ʻia ka ʻaelike hūnā
3) ʻEhiku lā hoʻihoʻi hōʻoia
ʻOi aku ka mea nui: hiki iā mākou ke hāʻawi i ka huahana wale nō, akā ʻo ka lawelawe ʻenehana hoʻonā!
He mea hana mākou, aia kā mākou hale hana ma Shandong, akā hiki iā mākou ke hāʻawi i kahi lawelawe kūʻai kūʻai hoʻokahi no ʻoe!

≤25kg: i loko o ʻekolu mau lā hana ma hope o ka loaʻa ʻana o ka uku. ＞25kg: hoʻokahi pule
Loaʻa, hiki iā mākou ke hāʻawi i nā laʻana liʻiliʻi liʻiliʻi no ke kumu loiloi maikaʻi!
1kg no ka ʻeke fpr samples, 25kg a i ʻole 50kg no ka pahu, a i ʻole e like me kou makemake.
E mālama i ka pahu i paʻa paʻa i kahi maloʻo, anuanu a maikaʻi hoʻi.
