Description

[(Octylimino)Bis(Methylene)]Bisphosphonic Acid CAS NO 5995-31-3 is a high-purity organophosphorus compound belonging to the bisphosphonate class, valued for its exceptional chelating and scale inhibition properties. This chemical is critical for industrial processes requiring precise control over metal ions and mineral deposition. It is primarily sought by manufacturers in the water treatment, oilfield, and detergent industries for formulating high-performance additives and inhibitors.

Application

• Industrial Water Treatment: Acts as a highly effective scale and corrosion inhibitor in cooling towers, boilers, and reverse osmosis systems.
• Oilfield Chemicals: Used in drilling and production fluids to control scale formation, particularly from barium sulfate and calcium carbonate, in harsh downhole conditions.
• Detergent & Cleaning Formulations: Serves as a powerful builder and sequestrant to inactivate water hardness ions (Ca²⁺, Mg²⁺), enhancing surfactant efficiency.
• Pulp & Paper Processing: Employed as a chelant in bleaching processes and to control scale in digesters and paper machines.
• Textile Auxiliaries: Functions as a stabilizer and sequestrant in dyeing and finishing baths to prevent metal-ion interference.
• Personal Care Products: Incorporated in select formulations as a stabilizing agent for its chelating action.
