Description

Heptapotassium Pentahydrogen [Ethane-1,2-Diylbis[[(Phosphonatomethyl)Imino]Ethane-2,1-Diylnitrilobis(Methylene)]]Tetrakisphosphonate is a high-performance, multi-phosphonate chelating agent and scale inhibitor. This compound is engineered for superior sequestration of di- and trivalent metal ions, making it a critical component in applications requiring precise water chemistry control. It is primarily utilized by industrial water treatment, detergent formulation, and oilfield chemical sectors where robust performance under demanding conditions is essential.

Application

• Industrial Water Treatment: As a highly effective scale and corrosion inhibitor in cooling towers, boilers, and reverse osmosis systems.
• Detergent & Cleaning Formulations: Acts as a powerful builder and sequestrant to enhance cleaning efficiency by inactivating water hardness ions.
• Oilfield Chemicals: Used in scale squeeze treatments and as a component in drilling fluids to prevent mineral scale deposition in wells and production equipment.
• Pulp & Paper Processing: Serves as a chelant in bleaching processes and a dispersant to control deposits.
• Textile Processing: Utilized as a stabilizer and sequestrant in peroxide bleaching and dyeing baths.
• Personal Care Products: Incorporated as a chelating agent in formulations to improve stability and efficacy.

Quality Control

Our production of Heptapotassium DTPMP adheres to stringent quality management protocols. Each batch undergoes comprehensive analytical testing to ensure consistent purity and performance. Certificates of Analysis (COA) detailing assay, active content, pH, and impurity profiles are provided and available upon request, supporting compliance with relevant industry standards.

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). Due to its hygroscopic nature, the container must be kept tightly sealed after opening to prevent moisture absorption, which can affect product performance and handling.
