Description

(1-Aminoethylidene)Bisphosphonic Acid is a high-purity, nitrogen-containing bisphosphonate compound with significant chelating and scale-inhibiting properties. Its molecular structure makes it a highly effective agent for controlling mineral precipitation and corrosion in demanding industrial water systems. This product is essential for manufacturers and formulators in the water treatment, detergent, and pharmaceutical intermediate sectors seeking reliable performance and supply chain consistency. We provide this material with a focus on batch-to-batch uniformity and technical support for your specific application needs.

Application

• Industrial Water Treatment: Acts as a highly effective scale and corrosion inhibitor in cooling water, boiler water, and reverse osmosis systems, particularly against calcium carbonate and sulfate scales.
• Detergent & Cleaning Formulations: Serves as a superior builder and sequestrant to inactivate water hardness ions (Ca²⁺, Mg²⁺), enhancing the cleaning efficiency of industrial and institutional detergents.
• Pharmaceutical Intermediates: Used in the synthesis of bisphosphonate drugs for the treatment of bone disorders such as osteoporosis and Paget's disease.
• Oilfield Chemicals: Applied in scale squeeze treatments and as an additive in drilling fluids to prevent mineral scale formation in downhole equipment.
• Textile & Pulp/Paper Processing: Functions as a chelating agent to control metal ion interference during bleaching, dyeing, and pulping operations, improving process efficiency and product quality.
• Personal Care Products: Incorporated in formulations as a stabilizing agent and to enhance the performance of other active ingredients.

Quality Control

Our (1-Aminoethylidene)Bisphosphonic Acid is manufactured under a strict quality management system. Every batch undergoes rigorous analytical testing to ensure it meets precise specifications for identity, purity, and performance. A comprehensive Certificate of Analysis (COA) documenting key parameters such as assay, impurity profile, and physical characteristics is provided with each shipment 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 affect quality.
