Description

Tridecaammonium Hydrogen [[(Phosphonatomethyl)Imino]Bis[Ethylene[(Phosphonatomethyl)Imino]Ethylenenitrilobis(Methylene)]]Tetrakisphosphonate is a highly effective, multi-dentate chelating agent and scale inhibitor belonging to the class of polyamino polyphosphonates. Its complex molecular structure provides exceptional sequestration power for di- and trivalent metal ions, such as calcium, magnesium, iron, and copper, across a wide pH range. This product is essential for industries requiring superior water treatment, corrosion inhibition, and deposit control in complex aqueous systems.

Application

• Industrial Water Treatment: Primary application as a high-performance scale and corrosion inhibitor in cooling water systems, boiler water treatment, and desalination plants.
• Oilfield Chemistry: Used in scale squeeze treatments and as an additive in drilling and completion fluids to control mineral scaling in downhole and production equipment.
• Pulp & Paper Industry: Acts as a chelant and dispersant to control metal-ion catalyzed decomposition of hydrogen peroxide and other bleaching chemicals.
• Textile Processing: Serves as a stabilizer and sequestrant in peroxide bleaching baths to prevent catalytic damage to fabrics.
• Detergent & Cleaning Formulations: Incorporated as a builder to enhance cleaning efficiency by inactivating water hardness ions and preventing soap scum.
• Metal Surface Treatment: Used in electroplating and metal cleaning solutions to complex interfering metal ions and improve process quality.

Quality Control

Our production of Tridecaammonium Hydrogen Polyphosphonate adheres to stringent quality management protocols. Every batch undergoes comprehensive analytical testing, including assay, identification, and impurity profile analysis, to ensure consistent performance and purity. Certificates of Analysis (COA) documenting key parameters such as active content, pH, density, and color are available upon request to support your quality assurance and regulatory needs.

Storage

Preserve in a tightly closed container, protected from light. Store in a cool, dry, well-ventilated area at room temperature (15-25°C). This material is hygroscopic (moisture-sensitive). Keep the container tightly sealed when not in use to prevent absorption of atmospheric moisture, which may affect product quality.
