Description

Gentiobiose is a disaccharide sugar composed of two glucose units linked by a β(1→6) glycosidic bond. This unique structure makes it a valuable biochemical tool and a key intermediate in the study of carbohydrate metabolism and enzymatic processes. It is primarily utilized by researchers and manufacturers in the life sciences, pharmaceutical development, and specialty chemical synthesis sectors. The product is supplied under the identifier CAS No. 554-91-6.

Application

• Biochemical Research: Used as a standard and substrate in enzymatic studies, particularly for β-glucosidases and other glycosyl hydrolases.
• Pharmaceutical Development: Serves as a chiral building block or intermediate in the synthesis of complex glycoconjugates and potential therapeutic agents.
• Food Science & Analysis: Employed as a reference compound in chromatography for analyzing oligosaccharide profiles in food products like honey and certain fermented beverages.
• Cosmetic & Personal Care: Investigated for potential use in skincare formulations due to its humectant and mild exfoliating properties derived from its sugar structure.
• Diagnostic Reagents: Can be incorporated into kits and assays for clinical diagnostics related to carbohydrate digestion and metabolic disorders.
• Plant & Microbial Physiology: Used to study plant defense mechanisms and microbial recognition processes involving specific carbohydrate motifs.

Quality Control

Our Gentiobiose is produced and tested under a strict quality management system. Each batch undergoes comprehensive analytical testing, including HPLC for purity and spectroscopic identification (IR, NMR), to ensure it meets the high standards required for research and development. A detailed Certificate of Analysis (COA) is provided with every shipment, confirming compliance with specified parameters.

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, which can affect stability and handling properties.
