| | β-D-Glucose pentaacetate Usage And Synthesis |
| Chemical Properties | white to beige powder | | Uses | β-D-Glucose Pentaacetate is used in biochemical reaction and also used as an active pharmaceutical intermediate. Further, it is used to stimulate insulin release in rat pancreatic islets. | | Uses | beta-D-Glucose pentaacetate was reported to stimulate insulin release in rat pancreatic islets. | | Definition | ChEBI: Beta-d-glucose pentaacetate is an organooxygen compound. It is functionally related to a hexacarboxylic acid. | | Purification Methods | Crystallise the pentaacetate from MeOH or EtOH. It is best purified by recrystallising 160g from 1L of hot 95% EtOH (charcoal) and filtering hot. It is important that as soon as the temperature of the filtrate cools to ~20o it is filtered off. Note that some -D-isomer will crystallise out if a prolonged crystallisation period is allowed. Further crystallisation in this manner and drying in a vacuum over CaCl2 will give pure -D-anomer which has m 132o, [] D 20 + 4o (c 5, CHCl3).
