Description

Pentasodium 2-[Oxidobis[4-(Phosphonnatooxy)Phenyl]Methyl]Benzoate is a high-purity, multi-functional organic phosphate salt complex. This compound is valued for its exceptional chelating and dispersing properties, making it a critical performance additive in demanding industrial processes. It is primarily utilized by manufacturers in the water treatment, textile processing, and detergent industries where control over scale and metal ions is paramount.

Application

• Industrial Water Treatment: Acts as a highly effective scale and corrosion inhibitor in cooling towers, boilers, and reverse osmosis systems.
• Detergent & Cleaning Formulations: Serves as a powerful builder and sequestrant to enhance cleaning efficiency by inactivating water hardness ions (calcium, magnesium).
• Textile Processing: Used as a dispersing and chelating agent in dyeing and bleaching baths to prevent metal-ion interference and improve color fastness.
• Pulp & Paper Manufacturing: Functions as a stabilizer and dispersant in bleaching processes (e.g., hydrogen peroxide stabilization) to improve pulp brightness and quality.
• Oilfield Chemicals: Employed in scale inhibition for downhole and production applications to prevent mineral deposition in pipes and equipment.
• Industrial Cleaners: A key component in heavy-duty alkaline and acid cleaners for industrial equipment and surfaces.

Quality Control

Our Pentasodium 2-[Oxidobis[4-(Phosphonnatooxy)Phenyl]Methyl]Benzoate is manufactured under a strict quality management system. Each batch undergoes rigorous analytical testing to ensure consistent purity and performance, meeting the specifications required for industrial applications. Certificates of Analysis (COA) documenting key parameters such as assay, pH, and impurity levels are available upon request.

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 initial use to prevent absorption of atmospheric moisture, which can lead to caking or reduced efficacy.
