Boric acid is commonly used for the preparation of buffers such as Tris-Borate-EDTA (TBE). Borate buffers have been used in capillary and gel electrophoresis for separating proteins and nucleic acids. The useful buffering range of boric acid is pH 8.2-10.1. In a basic solution, the salt of boric acid forms complex equilibria, with the tetraborate ion (B4O72-) being the most predominant species present. Boric acid is used in catalytic amounts to promote amidation between carboxylic acids and amines. It is capable of forming a complex with various carbohydrates, as well as with pyridine nucleotides, such as NAD+.
