Description

2-Phosphonobutane-1,2,4-Tricarboxylic Acid, Potassium Salt is a high-performance, multi-functional organic phosphonate widely recognized for its superior scale and corrosion inhibition properties. This compound is particularly valued for its excellent chelating power and stability across a wide pH range, making it a critical component in demanding industrial water treatment formulations. It is essential for chemical suppliers, formulators, and manufacturers in the water treatment, detergent, and textile processing industries seeking reliable and effective sequestrants.

Application

• Industrial Water Treatment: A key ingredient in cooling water and boiler water treatment programs for scale inhibition (e.g., calcium carbonate, sulfate) and corrosion control.
• Detergent & Cleaning Formulations: Acts as a powerful builder and sequestrant in liquid detergents, industrial cleaners, and dishwashing compounds to inactivate water hardness ions.
• Textile Processing: Used as a stabilizer in peroxide bleaching baths and as a dispersant and chelant in dyeing processes to improve color fastness and uniformity.
• Pulp & Paper Industry: Employed in bleaching sequences and as a dispersant to control metal ions that can catalyze degradation and affect paper brightness.
• Oilfield Applications: Functions as a scale inhibitor in squeeze treatments and production systems to prevent mineral scale deposition in wells and pipelines.
• Metal Surface Treatment: Used in metal cleaning and plating baths to sequester interfering metal ions and prevent precipitation.

Quality Control

Our 2-Phosphonobutane-1,2,4-Tricarboxylic Acid, Potassium Salt is manufactured under a strict quality management system. Each batch undergoes rigorous analytical testing to ensure consistent performance and meets high-purity standards suitable for industrial applications. Certificates of Analysis (COA) with key parameters such as active content, pH, and density are 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 product is hygroscopic (moisture-sensitive); ensure containers are kept tightly sealed to prevent absorption of atmospheric moisture which may lead to caking or reduced efficacy.
