2,6-Dihydroxypurine Chemical Properties,Uses,Production

Chemical Properties

White to off-white crystalline powder

Uses

Found in animal organs, yeast, patatoes, coffee beans, tea. This drug can be used to relax and widen certain breathing passages of the lungs. It is also found that a large number of derivatives have adenoside receptor antagonist properties.

Purification Methods

The monohydrate separates in a microcrystalline form on slow acidification with acetic acid of a solution of xanthine in dilute NaOH. It is also precipitated by addition of conc NH3 to its solution in hot 2N HCl (charcoal). After washing with H2O and EtOH, it is dehydrated by heating above 125o. Its solubility in H2O is 1 in 14,000parts at 16o and 1 in 1,500parts of boiling H2O, and separates as plates . It has no m, but the perchlorate has m 262-264o [Lister Purines Part II, Fused Pyrimidines Brown Ed, Wiley-Interscience pp252-253 1971, ISBN 0-471-38205-1]. [Beilstein 26 H 447, 26 I 131, 26 II 260, 26 III/IV 2327.]
