2,2'-Bicinchoninic Acid Chemical Properties,Uses,Production

Chemical Properties

Beige powder

Uses

2,2′-Biquinoline-4,4′-dicarboxylic acid has been used in a study that synthesized and structurally characterized six metal-organic coordination polymers.

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.
