2,2'-Biquinoline Chemical Properties,Usage,Production
Chemical Properties
SLIGHTLY YELLOW TO LIGHT BEIGE SHINY FLAKES
Uses
2,2'-Biquinoline is used as a reagent for spectrophotometric determination of Cu and as an indicator for titration of organolithium reagents, giving yellow-green charge-transfer complexes.
Application
2,2'-Biquinoline, also known as cuprous reagent, reacts with monovalent cupric ion to give a purple color. It is a highly selective reagent for the determination of cuprous. It can be utilized as a ligand in the synthesis of heteroleptic Cu(I) complexes for light-emitting diodes(LED) and cationic iridium(III) complexes as phosphorescent dyes for live-cell imaging.

Tetrahedron Letters, 15, p. 2373, 1974 DOI: 10.1016/S0040-4039(01)92259-2
General Description
2,2′-Biquinoline is a white crystalline solid and it melts at 176°C. It is insoluble in water, but is soluble in ethyl, amyl and isoamyl alcohol, isoamyl acetate, dimethylformamide, acetic acid, acetonitrile and carbon tetrachloride.
Purification Methods
Decolourise 2,2'-biquinolyl in CHCl3 solution (charcoal), then crystallise it to constant melting point from EtOH or pet ether [Cumper et al. J Chem Soc 1188 1962]. [Beilstein 23/10 V 8.]
