C5H10O5=150.13

Grade:BR

Content: ≥ 99.0% (GC)

Specific rotation: -13 ~ -15 º (c=4, H2O, NH3)

Physicochemical properties: one of the aldoses in pentose (pentose), which is an optical isomer with L (+) - lysose. It is an unnatural substance, which can be oxidized from calcium-d-galactate or oxidized with lactose γ It is formed by irradiation. Dextrose precipitated from the mixed solvent of ethanol and ether is a white hygroscopic monoclinic crystal, sweet and soluble in water. It is slightly soluble in ethanol. At 17 ℃, one sample can be dissolved in 38 parts of absolute ethanol. Density (20 ℃) 1.545g/cm3. DL lyxose has a melting point of 95 ℃. Melting point: 108 ~ 112 ℃

Purpose: biochemical research.
