L(+)-Rhamnose monohydrate

Product name:L(+)-Rhamnose monohydrate
CAS:10030-85-0
Molecular Formula:C6H14O6
Formula Weight:182.17
Specification:5g
Description:L(+) -rhamnose monohydrates are colorless crystalline powders, soluble in water and methanol, and slightly soluble in ethanol. The alpha contains a molecule of water, which is lost to heat and converted to beta (molecular weight 164.16). Type beta is extremely hygroscopic and converts to alpha by absorbing moisture in the air. The most common is alpha-l-rhamnotrin, which has a molecular weight of 182.11.

Under normal conditions, a-l-rhamnorelin monohydrate crystals were obtained. Melting point was 82 ~ 92℃, specific rotation was -7.7°→+8.9°, soluble in water and ethanol. Beta-l-rhamnotrin (anhydrating) is acicular crystal with hysteretic property, melting point is 122 ~ 126℃, +38.4°→+8.9°, soluble in water and ethanol. It has a sweet taste and is present in aqueous solution as pyrane.

It is reductive, oxidized with bromine water to produce rhamnoic acid and oxidized with nitric acid to produce l-arabinic trihydroxygodioic acid. L(+) -rhamnose monoglasses were tested with sodium amalgam.

L(+) -rhamnose monohydrates are used to determine the permeability of the intestines, as sweeteners, and to produce flavors and flavors.
