1,2,3,4-Di-O-Isopropylidene-alpha-D-galactopyranose CAS:4064-06-6

ʻO ka hopena nui o 1,2:3,4-Di-O-isopropylidene-D-galactopyranose ka pale ʻana i nā hui hydroxyl ma ka molekala galactose. Hoʻokō ʻia kēia ma ka hoʻokumu ʻana i kahi cyclic acetal derivative, kahi e ālai ai i ka reactivity o nā hui hydroxyl. ʻO kekahi noi o kēia hui i loko o ka kemika carbohydrate a me ka synthesis. Ma ka pale ʻana i nā hui hydroxyl, hiki i ka 1,2:3,4-Di-O-isopropylidene-D-galactopyranose ke hana i nā hopena koho ma nā hui hana ʻē aʻe, me ka ʻole o nā hopena makemake ʻole ʻia ma nā kūlana hydroxyl. ʻAe kēia i ka hoʻoponopono pono a me ka hoʻololi ʻana o ka molekala galactose. Eia kekahi, hiki ke hoʻohana ʻia kēia derivative i ka synthesis o nā huahana kūlohelohe like ʻole a me nā lāʻau lapaʻau e loaʻa ana nā moieties galactose. Kōkua ia i ke kūkulu ʻana i nā molekala paʻakikī, kahi e pono ai nā hopena i kāohi ʻia a koho ʻia. Eia kekahi, loaʻa i kēia hui nā noi i ka hana ʻana o nā kemika kūikawā, e like me nā surfactants a me nā polymers, kahi e makemake ʻia ai nā hoʻololi kikoʻī o nā molekala galactose. Ma keʻano holoʻokoʻa, ʻo ka hoʻohana ʻana i ka 1,2: 3,4-Di-O-isopropylidene-D-galactopyranose ma ke ʻano he mea pale e hiki ai i ka synthesis kūpono a me ka hoʻololi ʻana o nā hui galactose i loaʻa i nā ʻano like ʻole, me ka kemika organik, nā lāʻau lapaʻau, a me ka ʻepekema mea.
