Beschreibung

Allgemeine Beschreibung

β-cyclodextrin (β-CD), a well-known macrocyclic oligosaccharide member of the CD family, is composed of seven D-glucose units connected via α(1→4) glycosidic bonds. Its ability to form several inclusion complexes with organic as well as inorganic compounds makes it a potential candidate in solid and solution state determinations.

Anwendung

Forms clathrates. Produces a water-soluble complex with dansyl chloride (cat. no. D143359) for the fluorescent labeling of proteins.

β-Cyclodextrin hydrate may be used:

• To form an inclusion complex with norfloxacin for subsequent analysis using high performance liquid chromatography (HPLC).
• As a precursor of heptakis-(2,3-diacetyl-6-sulfato)-β-cyclodextrin for use as a chiral selector in the enantioseparation of linezolid by capillary electrophoresis (CE).
