Description

[[(2-Hydroxyethyl)Imino]Bis(Methylene)]Bisphosphonic Acid, Potassium Salt is a high-purity, water-soluble potassium salt of a phosphonic acid derivative. This compound is valued for its excellent chelating and scale inhibition properties, making it a critical component in formulations requiring superior metal ion control. It is primarily utilized by industries such as water treatment, industrial cleaning, and as a key intermediate in specialty chemical synthesis.

Application

• Industrial Water Treatment: Acts as a highly effective scale and corrosion inhibitor in cooling water systems, boilers, and reverse osmosis membranes.
• Detergent & Cleaning Formulations: Serves as a powerful builder and chelating agent in industrial and institutional cleaning products to enhance performance in hard water.
• Personal Care Products: Used in select cosmetic and personal care formulations as a stabilizer and sequestrant.
• Textile & Pulp Processing: Functions as a chelant and peroxide stabilizer in bleaching and dyeing processes.
• Oilfield Chemicals: Employed in scale inhibition treatments for oil and gas production to prevent mineral deposits in wells and equipment.
• Chemical Synthesis: A valuable intermediate for the production of more complex phosphonate compounds and metal surface treatment agents.

Quality Control

Our [[(2-Hydroxyethyl)Imino]Bis(Methylene)]Bisphosphonic Acid, Potassium Salt is manufactured under a strict quality management system. Every batch undergoes rigorous analytical testing to ensure it meets precise specifications for purity, identity, and performance. A comprehensive Certificate of Analysis (COA) documenting assay, impurity profile, and physical parameters is available upon request 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 to prevent absorption of atmospheric moisture, which can lead to caking or reduced efficacy.
