Chemical Property:

Molecular Formula C8H14Cl2N2O2
Molar Mass 241.11496
Melting Point 64.43 °C
Solubility Soluble in water giving a highly viscous solution, practically insoluble in organic solvents.
Appearance Yellow powder
Color Off-White to Pale Yellow
Merck 14,10057
Storage Condition Hygroscopic, -20°C Freezer, Under inert atmosphere
Stability Stable. Combustible. Incompatible with strong oxidizing agents.
Physical and Chemical Properties Milky white to light yellow-brown powder. Soluble in water at room temperature into a semi-transparent viscous liquid, insoluble in ethanol, isopropanol and acetone and other organic solvents. Xanthan gum aqueous solution has good viscosity and is quite stable in the range of -4~80 ℃, when the concentration of ethanol, isopropanol or acetone in water is more than 50% ~ 60%, it will cause the precipitation of xanthan gum. Acid and alkali resistance and resistance to biological enzyme degradation ability is very strong, in the range of pH 1.5~13, the viscosity of xanthan gum aqueous solution is not affected by pH value. Xanthan gum is a natural high molecular compound, rats oral LD50>10g/kg,ADI does not require special provisions (FAO/WHO,1994).
