| | XANTHOPTERIN MONOHYDRATE Usage And Synthesis |
| Chemical Properties | yellow to orange crystalline powder | | Uses | Xanthopterin (cas# 5979-01-1) is useful as a crystal nucleation of vinylidene chloride polymers. | | Uses | Biochemical research. | | Definition | Pigment
found in the wings of butterflies; can be converted
by yeast into folic acid. | | Purification Methods | Purification is as for isoxanthopterin (see “Heterocyclic Compounds”, Chapter 4). It is crystallised by acidifying a hot ammoniacal solution with formic acid, and collecting the crystals by centrifugation followed by washing with EtOH, ether and drying at 100o in vacuo. Its RF values on paper chromatography are 0.15 (n-PrOH, 1% aqueous NH3, 2:1), 0.36 (n-BuOH/AcOH/H2O, 4:1:1) and 0.47 (3% aqueous NH3).
