O-Desmethyl Quinine Usage And Synthesis

Chemical Properties

Pale Yellow Solid

Uses

A metabolite of Quinine (Q694000).

Definition

One of the cinchona alkaloids.

Purification Methods

Cupreine crystallises from EtOH (anhydrous crystals) and wet Et2O (as dihydrate crystals). It has Kb 2.7x10-7 [Kolthoff Biochem Z 162 323]. The sulfate forms needles, m 257o(dec), from MeOH, amyl alcohol or H2O, with [] 20-197.9o (c 1.2, H2O). [Beilstein 22 I 165, 22 II 416.]
