Description

Heptakis-(2,6-Di-o-Pentyl)-β-Cyclodextrin is a chemically modified cyclodextrin derivative where each glucose unit of the β-cyclodextrin core is alkylated with pentyl groups at the 2- and 6- positions. This modification significantly enhances its lipophilicity and alters its host-guest complexation properties compared to native cyclodextrins. It is a critical advanced material for research and development in separation sciences and analytical chemistry. This product is essential for scientists and manufacturers in the pharmaceutical, agrochemical, and specialty chemical industries who require highly selective molecular recognition agents for chiral separations, catalysis, and controlled release systems.

Application

• Chiral Stationary Phases (CSPs): A key selector for high-performance liquid chromatography (HPLC) and gas chromatography (GC) columns to separate enantiomers of pharmaceuticals and fine chemicals.
• Analytical Chemistry Reagent: Used as a chiral selector or complexing agent in capillary electrophoresis (CE) and other analytical techniques for method development and purity analysis.
• Catalysis & Synthesis: Acts as a supramolecular catalyst or nano-reactor in organic synthesis, facilitating reactions with enhanced selectivity and yield.
• Material Science: Incorporated into sensors, membranes, and functional coatings to impart selective molecular binding capabilities.
• Pharmaceutical Research: Employed in pre-formulation studies to investigate drug solubility, stability, and controlled release through host-guest inclusion complexes.
• Agrochemical Formulation: Explored for the encapsulation of active ingredients to improve stability, solubility, or reduce environmental impact.
