  • Applications

    Cyclotetraglucose pentahydrate (CAS 532945-76-9) is a cyclic oligosaccharide comprising four glucose units, and is used as a synthetic intermediate for oligosaccharide derivatives. In industry, its applications typically span several areas: (1) a scaffold and precursor for synthesizing carbohydrate-derived derivatives; (2) host–guest chemistry and encapsulation to host, protect, or stabilize active ingredients in formulations; (3) an excipient in pharmaceutical formulations to support processing and formulation stability; (4) a carrier in cosmetics for active ingredients or as a stabilizing component; (5) a functionalizable scaffold for polymers and coatings, enabling crosslinking or further modification; (6) a research tool in analytical chemistry and separation science, including use as a potential chiral selector.
