TL;DR: Phytoene, a new noncrystalline, colorless polyene, has been isolated from tomatoes and carrot oil by an improved adsorptive procedure and produced a very weak Carr-Price reaction, but it did give a characteristic color reaction with the Liebermann-Burchard test.

TL;DR: In this paper, a 2:2′-biquinolyl, prepared by catalytic dehydrogenation of quinoline, has been found to give a purple colour with the cuprous ion under certain conditions.
Abstract: 2:2′-Biquinolyl, prepared by catalytic dehydrogenation of quinoline, has been found to give a purple colour with the cuprous ion under certain conditions. The colour reaction is sensitive, specific for copper, and the intensity of the colour produced follows Beer's law. A procedure has been worked out for the detection and estimation of copper, the smallest amount of copper detectable being 1 part in 100,000,000. Stable complexes with cupric copper and cobalt have also been prepared.
