Description

6-o-(Galactopyranosyl)Cyclomaltoheptaose is a specialized, high-purity cyclodextrin derivative where a galactopyranosyl moiety is attached to the primary hydroxyl side of β-cyclodextrin. This molecular modification significantly enhances its solubility and complexation capabilities compared to native cyclodextrins, making it a superior host molecule for encapsulating sensitive or poorly soluble compounds. It is primarily utilized in advanced pharmaceutical formulations, nutraceutical delivery systems, and high-value cosmetic applications where precise molecular encapsulation and stabilization are critical.

Application

• Pharmaceutical Solubility & Bioavailability Enhancement: As a complexing agent to improve the aqueous solubility, stability, and bioavailability of active pharmaceutical ingredients (APIs).
• Advanced Drug Delivery Systems: Used in the formulation of controlled-release and targeted drug delivery platforms, including nanoparticles and inclusion complexes.
• Nutraceutical & Functional Food Stabilization: Protects sensitive bioactive compounds like vitamins, flavors, and pigments from degradation, masking unpleasant tastes and odors.
• Cosmetic & Personal Care Actives: Stabilizes volatile fragrances and active ingredients in creams and serums, controlling their release and reducing skin irritation.
• Analytical Chemistry & Chiral Separation: Serves as a chiral selector in capillary electrophoresis and HPLC for the separation of enantiomers.
• Biochemical Research & Enzyme Modeling: Used as a molecular scaffold in supramolecular chemistry and enzyme mimicry studies due to its well-defined cavity.

Quality Control

Our 6-o-(Galactopyranosyl)Cyclomaltoheptaose is manufactured under a strict quality management system. Each batch undergoes comprehensive analytical testing, including HPLC for purity, NMR for structural confirmation, and specific tests for residual solvents and moisture, to ensure it meets the high standards required for pharmaceutical and food-grade applications. A detailed Certificate of Analysis (COA) is provided with every shipment, and we support compliance with cGMP, ICH Q7 guidelines, and REACH regulations.

Storage

Preserve in a tightly closed container, protected from light. Store in a cool, dry, and well-ventilated area at a controlled room temperature (15-25°C). This product is hygroscopic (moisture-sensitive) and must be kept under dry, inert conditions to prevent clumping and decomposition. For long-term storage, consider desiccated environments.
