Abstract
Abstract It is proposed to use numbers in base 16 (Hex) for an abbreviated designation of chlorobiphenyls. Values assigned to substituents in positions 2, 3, 4, and 5 are 1, 2, 4, and 8, respectively. These are added and expressed in Hex. Substitutions in positions 6 and 6′ are given values of 1 and 2. The designation is a three-digit number, the digits from left to right referring to the first ring, primed ring, and to substituents in the 6 positions, respectively. In the shorthand notation, BD1h stands for 2, 2′, 3, 4′, 5, 5′, 6-heptachlorobiphenyl (h indicates Hex).
