说明

一般描述

Heptakis(2,3,6-tri-O-methyl)-β-cyclodextrin is a β-cyclodextrin derivative that finds potential use in pharmaceutical, food and cosmetic applications. Its attractive features include: the non-polar cavity desirable for its use as a molecular host for a wide range of molecules and its affinity for organic compounds in solution as well as crystalline phases.[1]
 

应用

Heptakis(2,3,6-tri-O-methyl)-β-cyclodextrin may be used:
  • To investigate the crystal structure of its complexes with m-iodophenol, 4-biphenylacetic acid[2] and (R)- and (S)-flurbiprofen[3] by X-ray analysis.
  • To study the candidature of its complex with vitamin A for potential application as a drug delivery system for ophthalmic applications by high sensitivity fluorescence spectrometry and high pressure liquid chromatography (HPLC).[4]
  • In the determination of analyte composition in commercial samples by HPLC coupled to mass spectrometry (MS).[5]
