Description

β-Cyclodextrin Phosphate Sodium Salt is a chemically modified cyclodextrin derivative where phosphate groups are introduced to enhance its solubility and complexation properties. This modification is critical for creating stable, water-soluble inclusion complexes with a wide range of hydrophobic guest molecules. It is an essential advanced material for industries requiring precise molecular encapsulation, solubility enhancement, and stabilization of active ingredients in aqueous systems.

Application

• Pharmaceutical Formulations: Used as a solubility enhancer and stabilizer for poorly water-soluble APIs (Active Pharmaceutical Ingredients), improving bioavailability and shelf-life.
• Cosmetics & Personal Care: Functions as a delivery system for fragrances, vitamins, and active compounds in creams, lotions, and serums, controlling release and improving stability.
• Food & Nutraceuticals: Employed to encapsulate flavors, colors, vitamins, and ω-3 fatty acids, masking unpleasant tastes and protecting sensitive ingredients from oxidation.
• Analytical Chemistry & Diagnostics: Serves as a chiral selector in capillary electrophoresis and HPLC columns for enantiomer separation, and as a component in sensor materials.
• Agrochemicals: Enhances the solubility and environmental stability of pesticides and herbicides, allowing for more efficient and controlled application.
• Research & Development: A key reagent in supramolecular chemistry for studying host-guest interactions and developing novel drug delivery systems and nanomaterials.

Quality Control

Our β-Cyclodextrin Phosphate Sodium Salt is manufactured under a strict quality management system. Each batch undergoes rigorous analytical testing to ensure identity, purity, and consistency. We provide comprehensive Certificates of Analysis (COA) with key parameters such as assay, degree of substitution, residual solvents, and microbiological data. Production can be aligned with cGMP guidelines for pharmaceutical applications upon request.

Storage

Preserve in a tightly closed container, protected from light. Store in a cool, dry, and well-ventilated place at room temperature (15-25°C). This product is hygroscopic (moisture-sensitive). Keep the container tightly sealed in a dry environment to prevent absorption of moisture from the air, which can affect product performance and stability.
