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

Qhov cuam tshuam tseem ceeb ntawm 1,2:3,4-Di-O-isopropylidene-D-galactopyranose yog los tiv thaiv cov pab pawg hydroxyl ntawm cov molecule galactose. Qhov no yog ua tiav los ntawm kev tsim cov cyclic acetal derivative, uas thaiv cov reactivity ntawm cov pab pawg hydroxyl. Ib qho kev siv ntawm cov tshuaj no yog nyob rau hauv carbohydrate chemistry thiab synthesis. Los ntawm kev tiv thaiv cov pab pawg hydroxyl, 1,2:3,4-Di-O-isopropylidene-D-galactopyranose ua rau muaj kev xaiv cov tshuaj tiv thaiv ntawm lwm cov pab pawg ua haujlwm, tsis muaj cov tshuaj tiv thaiv tsis xav tau ntawm cov hydroxyl txoj haujlwm. Qhov no tso cai rau kev tswj hwm zoo thiab kev hloov kho ntawm cov molecule galactose. Ntxiv mus, cov derivative no tuaj yeem siv rau hauv kev tsim cov khoom ntuj thiab cov tshuaj uas muaj galactose moieties. Nws pab txhawb kev tsim cov tshuaj molecules nyuaj, qhov twg xav tau kev tswj hwm thiab xaiv cov tshuaj tiv thaiv. Tsis tas li ntawd, cov tshuaj no muaj cov ntawv thov hauv kev tsim cov tshuaj tshwj xeeb, xws li surfactants thiab polymers, qhov twg xav tau kev hloov kho tshwj xeeb ntawm cov tshuaj galactose. Zuag qhia tag nrho, kev siv 1,2: 3,4-Di-O-isopropylidene-D-galactopyranose ua tus neeg sawv cev tiv thaiv ua rau muaj kev sib xyaw ua ke thiab kev hloov kho ntawm cov tshuaj galactose hauv ntau qhov chaw, suav nrog cov tshuaj organic, tshuaj, thiab cov ntaub ntawv tshawb fawb.
