Description

2-[2-(4-Dodecylphenoxy)Ethoxy]Ethyl Dihydrogen Phosphate is a specialized organophosphate surfactant and functional monomer. This compound is valued for its unique amphiphilic structure, combining a hydrophobic dodecylphenol chain with a hydrophilic phosphate ester group, which imparts excellent surface-active and chelating properties. It is primarily utilized in advanced material synthesis, industrial formulations, and as a key intermediate in the production of specialty polymers and additives.

Application

• Polymer & Resin Modification: Acts as a functional monomer or cross-linking agent to enhance adhesion, flame retardancy, and compatibility in acrylic, epoxy, and polyurethane systems.
• Surfactant & Emulsifier: Used in the formulation of high-performance industrial cleaners, metalworking fluids, and agrochemical emulsions due to its excellent wetting and dispersing characteristics.
• Lubricant & Fuel Additive: Serves as an anti-wear agent, corrosion inhibitor, and detergent dispersant in advanced lubricant oils and fuel formulations.
• Chelating Agent: Employed in water treatment and metal surface treatment processes to sequester metal ions such as calcium and magnesium.
• Pharmaceutical & Cosmetic Intermediates: Used in the synthesis of certain prodrugs and as an emulsifying agent in specialized cosmetic preparations.
• Textile & Leather Auxiliaries: Functions as a softening agent, antistatic agent, and dye-leveling agent in textile and leather processing.

Quality Control

Our production of 2-[2-(4-Dodecylphenoxy)Ethoxy]Ethyl Dihydrogen Phosphate adheres to a stringent quality management system. Every batch undergoes rigorous analytical testing, including assay by titration or HPLC, identification by IR spectroscopy, and control of key impurities such as free phenol and moisture content. Certificates of Analysis (COA) documenting purity, physical properties, and conformance to agreed specifications are provided with each shipment to ensure full traceability and compliance for your 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 material is hygroscopic (moisture-sensitive); the container must be kept tightly sealed to prevent absorption of atmospheric moisture, which can affect product quality and performance.
