Description

3A-Amino-3A-Deoxy-(2As,3As)-β-Cyclodextrin is a chemically modified derivative of β-cyclodextrin, featuring a primary amino group at the 3-position of one glucose unit. This functionalization is critical as it introduces a reactive site for covalent conjugation, significantly enhancing the molecule's ability to form stable inclusion complexes with a wide range of guest molecules. It is an essential advanced intermediate for researchers and manufacturers in the pharmaceutical, biotechnology, and analytical chemistry sectors who require precise molecular encapsulation, chiral separation, or targeted drug delivery systems.

Application

• Pharmaceutical Drug Delivery: Serves as a functionalized carrier for enhancing the solubility, stability, and bioavailability of poorly water-soluble active pharmaceutical ingredients (APIs).
• Chiral Separation & Analysis: Used as a chiral selector or stationary phase modifier in High-Performance Liquid Chromatography (HPLC) and Capillary Electrophoresis (CE) for the resolution of enantiomers.
• Bioconjugation & Sensor Development: The primary amino group enables covalent attachment to proteins, enzymes, or fluorescent probes for creating biosensors and diagnostic assays.
• Catalysis: Acts as a supramolecular host in catalytic systems to improve reaction selectivity and efficiency by encapsulating catalysts or substrates.
• Cosmetic & Personal Care Formulations: Employed to stabilize fragrances, vitamins, and other sensitive ingredients in creams and lotions.
• Food & Flavor Technology: Used to mask unpleasant tastes, protect flavors from oxidation, and control the release of aroma compounds.
