Description

β-D-Glucopyranosyl(1-4)-D-Glucopyranose is a disaccharide sugar, commonly known as cellobiose, formed by the condensation of two glucose molecules. It serves as a fundamental building block and model compound in carbohydrate chemistry and enzymology research. This high-purity chemical is essential for manufacturers and researchers in the pharmaceutical, food science, and biotechnology industries who require a reliable and consistent substrate for analytical methods, enzymatic studies, and product development.

Application

• Biochemical Research: Used as a standard and substrate for studying the activity and kinetics of β-glucosidase and cellulase enzymes.
• Pharmaceutical Excipient Development: Investigated as a potential carrier or stabilizer in drug formulation due to its non-reducing sugar properties.
• Food & Beverage Analysis: Employed as an analytical reference standard in chromatography (HPLC, GC) for quantifying sugars in complex matrices.
• Microbiology & Fermentation: Serves as a selective carbon source in microbial culture media for specific bacterial strains.
• Cosmetic Science: Explored for its humectant and skin-conditioning properties in personal care product formulations.
• Industrial Enzyme Production: Acts as an inducer or substrate in the fermentation process for producing cellulolytic enzymes.

Quality Control

Our β-D-Glucopyranosyl(1-4)-D-Glucopyranose is manufactured under a strict quality management system. Each batch is tested to ensure it meets high-purity standards suitable for research and industrial applications. A comprehensive Certificate of Analysis (COA) detailing purity, identity, and specific tests is provided with every shipment to guarantee traceability and consistency.

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). Due to its hygroscopic nature, the container must be kept tightly sealed after each use to prevent moisture absorption and caking.
