Application
2-Phosphonobutane-1,2,4-tricarboxylic acid (PBTCA, CAS 37971-36-1) is a high-performance organophosphonate used as a scale inhibitor and corrosion inhibitor in industrial water treatment. It exhibits exceptional calcium carbonate, calcium sulfate, and barium sulfate scale inhibition even at low concentrations, with excellent thermal stability and resistance to chlorine oxidation. PBTCA is widely applied in cooling water systems, boiler water treatment, reverse osmosis (RO) processes, and oilfield water injection. It also functions as a chelating agent for metal ions, dispersant for particulate matter, and stabilizer for hydrogen peroxide and bleach formulations. Its low phosphorus content and high efficiency make it environmentally favorable. Xinchem offers custom synthesis, custom chemical synthesis, and contract manufacturing of high-purity PBTCA with flexible scaling from R&D to commercial tons.
