Product Name:D(+)-Raffinose Pentahydrate
English Name:D(+)-Raffinose Pentahydrate
CAS No.:17629-30-0
Aliases:Raffinose
Molecular Formula:C18H42O21
Physical Properties:White crystalline powder, crystallized from aqueous solution as pentahydrate. Slowly loses water of crystallization when heated to 100°C. Anhydrous form melts at 118–119°C; pentahydrate melts at 78–80.5°C. Density 1.465 g/cm³, refractive index 1.676 (predicted). Soluble in water (approx. 14 g/100 mL at 20°C), very slightly soluble in ethanol, soluble in pyridine, slightly soluble in alcohol. Optically active (dextrorotatory).
Uses:Raffinose is a natural functional trisaccharide that acts as a prebiotic to promote the proliferation of bifidobacteria and improve intestinal function. It is used in the food industry as a sweetener, humectant and stabilizer for antioxidants. In pharmaceuticals, it serves as a lyoprotectant and excipient. It is also used in microbial culture media and biochemical research.
