D-Fructose, CAS:57-48-7

D-Fructose, is a important constituent of sucrose, found in many plants storage organs, which contributes to fruit sweetness and is a major source of calories in fruit consumption.Pharmaceutical secondary standards for application in quality control, provide pharma laboratories and manufacturers with a convenient and cost-effective alternative to the preparation of in-house working standards.Fructose-1P, also known as D-fructose or levulosa baxter, belongs to the class of organic compounds known as monosaccharides. Monosaccharides are compounds containing one carbohydrate unit not glycosidically linked to another such unit, and no set of two or more glycosidically linked carbohydrate units. Monosaccharides have the general formula CnH2nOn. Fructose-1P exists in all eukaryotes, ranging from yeast to humans.Keto-D-fructose is the open-chain form of D-fructose. It is a keto-fructose and a D-fructose. It is an enantiomer of a keto-L-fructose.A monosaccharide in sweet fruits and honey that is soluble in water, alcohol, or ether. It is used as a preservative and an intravenous infusion in parenteral feeding.Title:?FructoseCAS Registry Number:?57-48-7CAS Name:?D-FructoseAdditional Names:?b-D-fructose; levulose; fruit sugarTrademarks:?Fructosteril; Laevoral (Laevosan); Levugen; Laevosan (Laevosan)Molecular Formula:?C6H12O6Molecular Weight:?180.16Percent Composition:?C 40.00%, H 6.71%, O 53.28%Literature References:?Occurs in a large number of fruits, honey, and as the sole sugar in bull and human semen: Auerbach, Bodlander,?Angew.

An aq soln at 20? contains about 20% of the furanose form.Properties:?Orthorhombic, bisphenoidal prisms from alc, dec 103-105?. Sweetest of the sugars. Shows mutarotation. [a]D20?-132? to -92? (c = 2). Rapid and anomalous mutarotation involves pyranose-furanose interconversion. The final value is obtained instantly in the presence of hydroxyl ions. pKa (18?): 12.06. Freely sol in water. One gram dissolves in 15 ml alc, in 14 ml methanol. Slightly sol in cold, freely in hot acetone; sol in pyridine, ethylamine, methylamine.pKa:?pKa (18?): 12.06Optical Rotation:?[a]D20?-132? to -92?
