5,6-二羟基吲哚-2-羧酸是黑色素合成过程中的中间体。5,6-二羟基吲哚-2-羧酸可能互变异构成多巴色素。5，6-二羟基吲哚-2-羧酸的低聚物可以形成阻转异构体，其很大程度上取决于单体间氢键的存在。5，6-二羟基吲哚-2-羧酸的这些异构体具有几乎相等的稳定性，并以其电荷转移性质为特征。富含5,6-二羟基吲哚-2-羧酸的低聚物可形成具有高电导率的材料的合适基础。 5,6-Dihydroxyindole-2-carboxylic Acid is an intermediate in the process of melanin synthesis. It may be possible for 5,6-Dihydroxyindole-2-carboxylic Acid to tautomerize into Dopachrome. The oligomers of 5,6-Dihydroxyindole-2-carboxylic Acid can form atropisomers that are strongly dependent on the presence of inter-monomer hydrogen bonds. These isomers of 5,6-Dihydroxyindole-2-carboxylic Acid have almost equivalent stability, and are characterized by their charge transfer properties. Oligomers rich in 5,6-Dihydroxyindole-2-carboxylic Acid may form a suitable basis for materials with high conductivity.
