Product name:D-Glucurone
CAS:32449-92-6
Molecular Formula:C6H8O6
Formula Weight:176.12
Specification:25g
Description:D-Glucurone is D- glucuronic acid - lactone. According to dry products, the content of C6H8O6 should be 98.5 ~ 102.0 %. D-Glucurone is white crystal or crystalline powder. No smell, slightly bitter taste; Meet the light color gradient deep; Soluble in water, a part of the lactone into glucuronic acid, achieve an equilibrium state, acid reaction.
D - Glucurone, precision said, adding water to dissolve and quantitative dilution into each 1 ml contains about 0.1 g solution, determination (appendix Ⅵ E) in accordance with the law, at 25 ℃ than curl is + 18.0 ° and 20.0 °.
About 0.5g of d-glucurone was taken for precise weighing, 50ml of d-glucurone was added, 50ml of newly boiled and cooled water below 20℃ was dissolved, 50ml of sodium hydroxide titrant (0.1mol/L) was added for precision at 20℃ and mixed, 3 drops of phenolphthalein indicator solution was added, and titrated with hydrochloric acid titrant (0.1mol/L) immediately, until the red color disappeared completely, and the titration result was corrected by blank test. Every 1ml of sodium hydroxide titration solution (0.1mol/L) is equivalent to 17.61mg of C6H8O6.
