The molecule of the title compound, C~15~H~26~Cl~2~, is built up from two fused six-membered and seven-membered rings. The six-membered ring has a perfect chair conformation, whereas the seven-membered ring displays a twist-chair conformation. A weak CβH...Cl hydrogen-bonding interaction links the m

A method is described for the qualitative and quantitative determination of configurational isomers of zeaxanthin (= 3,3' -dihydroxy-P, p -carotene) and lutein (= 3 3 -dihydroxya-carotene). It is based on the reaction of these zeaxanthin and lutein isomers with (S)-(+)-e-(l -naphthyl) ethyl isocyana
