Description

Heptakis(2,3-Dimethyl)-β-Cyclodextrin is a chemically modified cyclodextrin derivative, specifically engineered to enhance solubility and molecular encapsulation capabilities. This product is critical for overcoming formulation challenges related to poor aqueous solubility and stability of active compounds. It is primarily utilized by researchers and manufacturers in the pharmaceutical, agrochemical, and specialty chemical industries for applications in drug delivery, analytical chemistry, and catalysis.

Application

• Pharmaceutical Solubilization & Drug Delivery: Acts as a complexing agent to improve the aqueous solubility, stability, and bioavailability of poorly soluble active pharmaceutical ingredients (APIs).
• Analytical Chemistry & Chiral Separation: Employed as a chiral selector in capillary electrophoresis (CE) and high-performance liquid chromatography (HPLC) for the separation and analysis of enantiomers.
• Catalysis & Chemical Synthesis: Serves as a supramolecular catalyst or a reaction medium modifier to enhance reaction rates and selectivities in organic synthesis.
• Agrochemical Formulations: Used to enhance the solubility and efficacy of certain pesticides and herbicides in aqueous-based formulations.
• Food & Flavor Industry: Can be applied for the stabilization and controlled release of flavors, fragrances, and sensitive nutrients.
• Material Science: Utilized in the development of functional materials, sensors, and nano-carriers due to its well-defined cavity and host-guest properties.
