Indicator for complexometric titrations. | [Purification Methods]
The sample may be grossly contaminated with uramil, alloxanthine, etc., and may be difficult to purify. It is better to synthesise it from pure alloxanthine [Davidson J Am Chem Soc 58 1821 1936]. Recrystallise it from water. [Kuhn & Lyman Chem Ber 69 1547 1936, Beilstein 25 I 709, 25 III/IV 4236.] |
