CAS 4064-06-6: 1,2:3,4-Di-O-isopropilidene-α-D-galattopiranosio
Descrizione:
1,2:3,4-Di-O-isopropilidene-α-D-galattopiranosio è un derivato dei carboidrati, specificamente una forma protetta di α-D-galattopiranosio. Questo composto presenta due gruppi isopropilidene che servono a proteggere i gruppi idrossilici sullo zucchero, migliorando la sua stabilità e reattività nelle applicazioni sintetiche. È tipicamente un solido cristallino bianco a bianco sporco, solubile in solventi organici come il diclorometano e il metanolo, ma meno solubile in acqua a causa dei suoi gruppi isopropilidene idrofobici. La presenza di questi gruppi protettivi consente reazioni selettive in posizioni specifiche sulla molecola di zucchero, rendendolo prezioso nella sintesi organica e nella chimica dei carboidrati. Il composto è spesso utilizzato nella sintesi di carboidrati più complessi e glicosidi, facilitando lo studio delle reazioni di glicosilazione. La sua struttura può essere analizzata utilizzando tecniche come NMR e spettrometria di massa, che forniscono informazioni sulla sua configurazione molecolare e purezza. In generale, 1,2:3,4-Di-O-isopropilidene-α-D-galattopiranosio è un intermedio importante nella chimica dei carboidrati.
