2,2'-BICINCHONINIC ACID Usage And Synthesis

Chemical Properties

Beige powder

Purification Methods

Dissolve the acid in dilute NaOH and precipitate it with acetic acid, filter, wash swell with H2O and dry it at 100o in a vacuum oven. Attempts to form a picrate failed. The methyl ester (SOCl2-MeOH) has m 165.6-166o. [Lesesne & Henze J Am Chem Soc 64 1897 1942, Brown et al. J Am Chem Soc 68 2705 1946, Beilstein 25 III/IV 1148.] For the di-K salt see entry in “Metal-organic Compounds” in Chapter 5.
