Description

4-o-(α-D-Glucopyranosyl)-D-Glucopyranose is a high-purity disaccharide sugar derivative, also known as alpha,α-trehalose, valued for its exceptional stability and non-reducing properties. This compound is critical for applications requiring a chemically inert and protective carbohydrate, particularly in stabilizing sensitive biological materials. It serves as a key ingredient for the pharmaceutical, biotechnology, and food science industries, where it functions as a stabilizer, cryoprotectant, and humectant.

Application

• Pharmaceutical Excipient & Stabilizer: Used in the formulation of biologics, vaccines, and labile APIs to prevent degradation during lyophilization and storage.
• Biotechnology Reagent: Acts as a cryoprotectant for cell cultures, enzymes, and other sensitive biomolecules.
• Food & Nutraceutical Ingredient: Employed as a mild sweetener, texturizer, and shelf-life extender in functional foods and supplements.
• Cosmetic Formulations: Functions as a natural moisturizing factor (NMF) and humectant in skincare products.
• Diagnostic Kits: Used as a stabilizer in dry reagent strips and assay components.
• Agricultural & Veterinary Products: Incorporated into formulations for seed coatings and animal health products to enhance stability.
