Description

n-(Phosphonoamidino)Sarcosine, Dipotassium Salt is a specialized organophosphorus compound that serves as a high-performance chelating and scale inhibition agent. Its unique molecular structure, featuring both phosphonate and amidino functional groups, provides superior sequestration of di- and trivalent metal ions under demanding conditions. This product is essential for formulators and process engineers in the water treatment, detergent, and industrial cleaning sectors who require advanced solutions for controlling scale and preventing metal-ion catalyzed degradation.

Application

• Industrial Water Treatment: A key component in cooling water and boiler water treatment formulations for the inhibition of calcium carbonate, calcium sulfate, and barium sulfate scale.
• Detergent & Cleaning Formulations: Used as a builder and sequestrant in industrial and institutional (I&I) cleaning products to enhance surfactant performance and prevent soap scum.
• Oilfield Chemicals: Employed in scale inhibitor packages for squeeze treatments and production chemicals to manage mineral scale in downhole and topside facilities.
• Pulp & Paper Processing: Acts as a chelant in bleaching and pulping processes to stabilize peroxides and control transition metal ions.
• Textile Auxiliaries: Utilized in dyeing and finishing baths to sequester hardness ions and improve color uniformity and fastness.
• Personal Care: Incorporated into specific cosmetic and toiletry formulations requiring high-efficiency chelation without compromising stability.

Quality Control

Our production of n-(Phosphonoamidino)Sarcosine, Dipotassium Salt adheres to a strict quality management system to ensure batch-to-batch consistency and performance reliability. Each lot undergoes rigorous analytical testing, including assay by titration or HPLC, identification by FT-IR, and control of key impurities and moisture content. Certificates of Analysis (COA) documenting all test results are provided and available upon request to support your quality assurance and regulatory compliance needs.

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 product is hygroscopic (moisture-sensitive). Keep the container tightly sealed when not in use to minimize exposure to atmospheric moisture, which can affect product quality and handling properties.
