ChEBI: A quinolinemonocarboxylic acid that is quinoline-2-carboxylic acid substituted by hydroxy groups at C-4 and C-8.Purification Methods
It is precipitated by the addition of 2N formic acid to its solution in hot 2M ammonia (charcoal). The solid is filtered off, dried in a vacuum at ~80o in the dark. UV (H2O) has nm ( M-1cm-1): 243 (30,000) and 342 (6,500). The methyl ester has m 262o (from MeOH). It forms Cu2+, Zn2+, Fe2+ and Fe3+ salts. [Beilstein 22 III/IV 2513.]????? ?? ?? ? ???
