β-D-Galactose pentaacetat

Beschreibung:

β-D-Galactose pentaacetat ist ein acetylierter Derivat von β-D-Galactose, einem Monosaccharid. Diese Verbindung zeichnet sich durch das Vorhandensein von fünf Acetylgruppen aus, die an die Hydroxylgruppen des Galactosemoleküls gebunden sind, was ihre Lipophilie und Stabilität im Vergleich zum ursprünglichen Zucker erhöht. Sie erscheint typischerweise als weißer bis off-white kristalliner Feststoff und ist in organischen Lösungsmitteln wie Chloroform und Aceton löslich, aber weniger löslich in Wasser aufgrund der Acetylierung. Der Acetylierungsprozess verändert die Reaktivität der Hydroxylgruppen, wodurch β-D-Galactose pentaacetat in verschiedenen chemischen Anwendungen nützlich ist, einschließlich als Schutzgruppe in der organischen Synthese. Ihre molekulare Struktur ermöglicht spezifische Wechselwirkungen in biochemischen Tests und Forschungen, insbesondere in Studien zur Chemie der Kohlenhydrate. Darüber hinaus kann sie in der Synthese von Glykosiden und anderen Derivaten verwendet werden, was zum Verständnis der Funktionalität von Kohlenhydraten in biologischen Systemen beiträgt. Wie bei vielen acetylierte Verbindungen ist es wichtig, β-D-Galactose pentaacetat mit Vorsicht zu behandeln und die entsprechenden Sicherheitsprotokolle zu befolgen.

CAS: 4163-60-4

1,2,3,4,6-Penta-O-acetyl-b-D-galactopyranose, also known as beta-D-galactose pentaacetate, has high chemical stability and long shelf life. This protected form of galactose is a key building block of any chemical synthesis of galactose-containing oligosaccharides or glycoconjugates. In the presence of Lewis acids it can be used as a glycosyl donor to make simple glycosides. In order to perform more complex galactosylations it can be converted into more reactive donors, such as glycosyl halides or thioglycosides.
