Diphenic acid Chemical Properties,Usage,Production

Description

2,2’Dicarboxybiphenyl acid is also known as diphenic acid, being a useful pharmaceutical intermediate and used in the synthesis of dyes. Diphenic acid derivatives have attracted great attention due to its possession of useful therapeutic properties. Many diphenic acids derivatives have the potential of lowering the risk of chronic diseases such as cancer, cardiovascular diseases and other pathologies. It is applied in many herbs and components of food. Diphenic acids derivatives can usually be found in fruits like blackberry, raspberry and strawberry.
