This chemical is primarily used as a flame retardant in various polymer materials, including polyamides and polyesters. Its phosphorus content helps to inhibit combustion by promoting char formation and reducing the release of flammable gases. It is also employed as a stabilizer in certain industrial processes to enhance the thermal and oxidative stability of materials. Additionally, it finds application in the production of specialty chemicals where phosphinic acid derivatives are required for specific functional properties. Its effectiveness in improving fire resistance makes it valuable in industries such as textiles, electronics, and construction materials.
