1, 2:5, 6-Di-O-isopropylidene-a-D-ribo-hexofuranos-3-ulose, CAS:10578-85-5

1,2:5,6-Di-O-isopropylidene-a-D-ribo-hexofuranos-3-ulose, This is a sugar that is found in the urine of reindeer and caribou. It was first identified in the urine of animals captured in Alaska during the winter months. It has been shown to be present in human urine, as well, but at lower concentrations. Radiocarbon dating has revealed that this sugar is produced seasonally, with higher levels being found during the winter months. The seasonal variation may be due to changes in diet or metabolism.CAS Number10578-85-5Product Name(3aR,5R,6aS)-5-((R)-2,2-Dimethyl-1,3-dioxolan-4-yl)-2,2-dimethyldihydrofuro[2,3-d][1,3]dioxol-6(3aH)-oneIUPAC Name5-(2,2-dimethyl-1,3-dioxolan-4-yl)-2,2-dimethyl-3a,6a-dihydrofuro[2,3-d][1,3]dioxol-6-olMolecular FormulaC??H??O?Molecular Weight258.27 g/molInChIInChI=1S/C12H18O6/c1-11(2)14-5-6(16-11)8-7(13)9-10(15-8)18-12(3,4)17-9/h6,9-10,13H,5H2,1-4H3InChI KeyBBJBIEZVAHWJOO-UHFFFAOYSA-NSMILESCC1(OCC(O1)C2=C(C3C(O2)OC(O3)(C)C)O)CSynonyms1,2:5,6-Bis-O-(1-methylethylidene)-?-D-ribo-hexofuranos-3-uloseCanonical SMILESCC1(OCC(O1)C2=C(C3C(O2)OC(O3)(C)C)O) CIsomeric SMILESCC1(OC[C@@H](O1)[C@@H]2C(=O)[C@@H]3[C@H](O2)OC(O3)(C)C)CCOA:Product name: 1,2:5,6-Di-O-isopropylidene-a-D-ribo-hexofuranos-3-ulose hydrate?CAS:?10578-85-5?(2847-00-9 for 1,2:5,6-Di-O- isopropylidene-a-D-ribo-hexofuranos-3-ulose)M.F.: C12H18O6? ?M.W.: 258.27? ? ?Batch No: 20130411? ??Quantity: 645gItemsStandardsResultsAppearanceWhite or off-white powderCompliesMS and NMRShould complyCompliesMelting point105??~??115?C110??~ 112??Specific optical rotation[?]D(H2O)42? ~ 46 ?44.6?Reducing Substances?0.5%CompliesHeavy Metals?0.002%CompliesLoss on drying?1.0%0.15%TLCOne spotOne spotAssayMin. 98%98.8%
