Used as a buffering agent in cleaning products and detergents to maintain stable pH levels, particularly effective in hard water. Employed in the formulation of corrosion inhibitors for metal treatment, cooling systems, water treatment, and boiler systems. Serves as a precursor in the synthesis of other boron-containing compounds used in chemical and refractory materials industries. Applied in electroplating baths to improve deposit quality and bath stability. Utilized in some agricultural formulations as a source of boron for plant nutrition. Also found in certain cosmetic and personal care products for pH control. Sometimes used in specific fire extinguishing chemicals.
