Biochemical research.

The Uses of XANTHOPTERIN MONOHYDRATE

Xanthopterin (cas# 5979-01-1) is useful as a crystal nucleation of vinylidene chloride polymers.

What are the applications of Application

Xanthopterin is a pigment first discovered in butterfly wings

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).
