Description

1-Phosphono-4-(3-Phenoxyphenyl) Butylsulfonic Acid Tripotassium Salt is a high-purity, organophosphorus compound valued for its unique combination of phosphonic and sulfonic acid functionalities in a single, water-soluble salt form. This chemical is engineered to deliver superior performance as a scale inhibitor and dispersant in demanding aqueous systems. It is primarily sought after by formulators and process engineers in the water treatment, industrial cleaning, and oilfield chemical sectors where controlling mineral scale and particulate fouling is critical for operational efficiency and equipment longevity.

Application

• Industrial Water Treatment: Acts as a highly effective threshold scale inhibitor for calcium carbonate, calcium sulfate, and barium sulfate in cooling towers, boilers, and reverse osmosis systems.
• Oilfield Production Chemicals: Used in squeeze treatments and continuous injection programs to prevent downhole and topside scale deposition, protecting well productivity and surface facilities.
• Detergent and Cleaning Formulations: Serves as a powerful builder and dispersant in industrial and institutional cleaning products, enhancing soil suspension and preventing redeposition.
• Pulp and Paper Processing: Functions as a dispersant and deposit control agent to manage pitch and stickies, improving paper machine runnability and product quality.
• Textile Auxiliary: Employed in dyeing and finishing baths to sequester metal ions and disperse impurities, ensuring consistent color and fabric quality.
• Metal Surface Treatment: Used in pickling and plating baths to control scale formation and improve surface finish.

Quality Control

Our production of 1-Phosphono-4-(3-Phenoxyphenyl) Butylsulfonic Acid Tripotassium Salt adheres to a strict quality management system. Every batch undergoes rigorous analytical testing, including assay by titration and impurity profile analysis, to ensure it meets precise specifications for active content and purity. Certificates of Analysis (COA) documenting these results are provided with each shipment and are available upon request to support your quality assurance protocols.

Storage

Preserve in a tightly closed container, protected from light. Store in a cool, dry, and well-ventilated area at room temperature (15-25°C). This material is hygroscopic (moisture-sensitive); the container must be kept tightly sealed after opening to prevent absorption of atmospheric moisture, which can lead to caking or reduced efficacy.
