Description

(2-Carboxyethylidene)Bisphosphonic Acid is a high-purity, multifunctional bisphosphonate compound with significant chelating and scale-inhibiting properties. Its unique molecular structure, featuring both phosphonic acid and carboxylic acid groups, makes it a highly effective agent for controlling mineral deposition and metal ion sequestration in demanding industrial processes. This chemical is essential for manufacturers and formulators in the water treatment, detergent, and personal care industries seeking advanced performance and stability in their products.

Application

• Industrial Water Treatment: A highly effective scale and corrosion inhibitor in cooling water systems, boilers, and reverse osmosis membranes, particularly for controlling calcium carbonate and sulfate scales.
• Detergent & Cleaning Formulations: Acts as a superior builder and chelating agent in laundry detergents and industrial cleaners, enhancing cleaning power by sequestering water-hardness ions like calcium and magnesium.
• Personal Care Products: Used in formulations for oral care (e.g., tartar control toothpaste) and skincare products for its stabilizing and chelating properties.
• Oilfield Chemicals: Employed in scale inhibitor formulations for squeeze treatments in oil and gas production to prevent mineral scale formation in wells and pipelines.
• Textile & Pulp Processing: Serves as a peroxide stabilizer and chelant in bleaching processes and as a dispersant to prevent redeposition of soils and dyes.
• Metal Surface Treatment: Functions as a corrosion inhibitor and sequestrant in metal cleaning, plating, and finishing baths.

Quality Control

Our (2-Carboxyethylidene)Bisphosphonic Acid is manufactured under a strict quality management system. Each batch undergoes comprehensive analytical testing to ensure it meets precise specifications for purity, identity, and performance. Certificates of Analysis (COA) documenting key parameters such as assay, pH, and impurity profiles are provided to guarantee supply consistency and reliability for your critical applications.

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); the container must be kept tightly sealed after opening to prevent absorption of atmospheric moisture, which can affect product quality and handling properties.
