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.

Application

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).

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

A method for the enantioseparation of linezolid, the first compound of a truly new class of antibiotics-the oxazolidinones, was developed. The elaborated method of linezolid enantiomers separation was successfully performed using an anionic single-isomer cyclodextrin-heptakis-(2,3-diacetyl-6-sulfato)-beta-cyclodextrin (HDAS-beta-CD) as a resolving agent

The aim of this study was to develop and validate a simple liquid-chromatography method, with good accuracy, reproducibility and sensitivity, for the quantification of norfloxacin in β-cyclodextrin inclusion complexes. In the method validation, the parameters evaluated were linearity, limits of
