Description

Raffinose CAS NO 6227-50-5 is a naturally occurring trisaccharide composed of galactose, glucose, and fructose. This high-purity carbohydrate is valued for its functional properties as a prebiotic fiber and a low-glycemic index sweetener. It serves as a critical raw material and research standard for manufacturers and scientists in the pharmaceutical, nutraceutical, and food science industries.

Application

• Pharmaceutical Excipient: Used as a stabilizer and bulking agent in lyophilized (freeze-dried) formulations and tablet manufacturing.
• Prebiotic Ingredient: Incorporated into functional foods and dietary supplements to selectively promote beneficial gut microbiota growth.
• Research & Diagnostic Reagent: Serves as a standard and substrate in biochemical research, microbiology, and diagnostic kit development.
• Food & Beverage Additive: Utilized as a texturizer, humectant, and low-calorie sweetener in specialized food products.
• Cell Culture & Cryopreservation: Acts as a cryoprotectant agent in the freezing and storage of biological samples and cell lines.
• Cosmetic Formulations: Employed in skincare products for its moisturizing and skin-conditioning properties.

Quality Control

Our Raffinose is manufactured under a strict quality management system. Each batch is tested to ensure it meets high-purity standards suitable for pharmaceutical and food-grade applications. A comprehensive Certificate of Analysis (COA), detailing parameters such as assay, optical rotation, and impurity profiles, is provided to guarantee traceability and batch-to-batch 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). This product is hygroscopic (moisture-sensitive); the container must be kept tightly sealed after opening to prevent absorption of atmospheric moisture.
