Boric Acid, anhydrous

BH₃O₃

Application: Boric Acid is a commonly used reagent in molecular biology for the preparation of buffers such as Tris Borate EDTA (TBE) and has applications in capillary and gel electrophoresis. Boric Acid is also noted in some studies to potentially have antibacterial and antifungal applications. This compound has also been employed in hardening steel, preservatives, manufacturing of cements, porcelain, enamels, glass, borates, artificial gems, in nickeling baths, painting, and photography. It is a precursor material for other boron compounds. A dilute water solution of boric acid is usually employed as a mild antiseptic and eyewash. Boric acid is too employed in leather manufacture, electroplating, weatherproofing fabrics and cosmetics.
