Polychlorinated terphenyls (PCT), a group of persistent, low‐volatile environmental pollutants are rarely investigated because of their high number of congeners and missing practicable analytical methods. Therefore, the proven strategy is pursued to define a set of reference substances that is analyzed representatively of all PCT. For this purpose, 29 tetra‐ to hepta‐chlorinated terphenyls are chosen,...
In the course of the development of a new and reliable analytical method for the PCT, a group of environmental contaminants, six coplanar terphenyl congeners were synthesized and characterized by means of spectroscopic methods. These congeners are 3,3″,4,4″,5-pentachloro-p-terphenyl, 3,3″,4,5,5″-pentachloro-p-terphenyl, 3,3″,4,5″-tetrachloro-m-terphenyl, 3,3″,4,4″,5-pentachloro-m-terphenyl, 3,3″,5,5′,5″-pentachloro-m-terphenyl,...
