L-Fructose(CAS: 7776-48-9)

L-Fructose (CAS: 7776-48-9) is a sweet, crystalline carbohydrate with a molecular weight of approximately 180.16 g/mol. It is highly soluble in water and forms a 1:1 complex with sodium ions. Chemically, fructose is less reactive than glucose and does not undergo mutarotation like glucose. It is a reducing sugar and can form glycosidic bonds with other monosaccharides.

L-Fructose can be synthesized through the inversion of D-fructose by L-iduronate 2-sulfatase, or by chemical inversion of D-fructose with NaBH4 in the presence of a base. Another method involves the enzymatic conversion of D-fructose to L-fructose using the enzyme D-fructose-L-iduronate 2-sulfotransferase. These methods yield L-fructose with high selectivity and good yield.

L-Fructose (CAS: 7776-48-9) is widely used in the food and beverage industry for its sweetness and low glycemic index. It is also employed in the pharmaceutical industry as a sweetener in medications, and in the polymer industry as a monomer in the production of polyols. Additionally, it has applications in the manufacturing of sensors and semiconductors.

When handling L-Fructose (CAS: 7776-48-9), it is important to wear appropriate personal protective equipment (PPE) such as gloves and safety goggles. Store the compound in a cool, dry place away from direct sunlight and heat sources. In case of a spill, use appropriate spill kits and follow the Material Safety Data Sheet (MSDS) or Safety Data Sheet (SDS) for proper clean-up procedures. Ensure adequate ventilation in the work area and use a fume hood when necessary.
