产品描述

General description

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.[3][1]

Application

β-Cyclodextrin hydrate may be used:
• To form an inclusion complex with norfloxacin for subsequent analysis using high performance liquid chromatography (HPLC).[4]
•  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).[2]
