Description

2-Hydroxyethyl 3-(Hydroxymethylphosphinoyl)Propionate is a specialized organophosphorus compound featuring a unique combination of hydroxyl, ester, and phosphinoyl functional groups. This structure makes it a valuable reactive intermediate and functional additive for advanced material synthesis. It is particularly sought after by R&D and production teams in the polymer and specialty chemical sectors for developing flame-retardant materials, adhesion promoters, and cross-linking agents. The compound's bifunctional nature allows for its incorporation into polymer backbones or use as a surface-modifying agent.

Application

• As a key monomer or co-monomer in the synthesis of flame-retardant polymers and coatings.
• As a reactive diluent or cross-linking agent in radiation-curable resins (e.g., UV-curable inks and adhesives).
• As a precursor for synthesizing phosphorus-containing surfactants and emulsifiers.
• In the formulation of adhesion promoters for coatings on difficult substrates.
• As a building block for metal-complexing agents and corrosion inhibitors.
• In research for developing novel biomaterials and drug delivery systems.
• As a modifier for improving the thermal stability and mechanical properties of engineering plastics.

Quality Control

Every batch of 2-Hydroxyethyl 3-(Hydroxymethylphosphinoyl)Propionate is manufactured and tested under a strict quality management system. We provide comprehensive analytical data to ensure the product meets your precise technical requirements. A Certificate of Analysis (COA) detailing purity, identity, and impurity profiles is supplied with each shipment and is available upon request.

Storage

Preserve in a tightly closed container, protected from light. Store in a cool, dry, and well-ventilated place at a controlled room temperature (15-25°C). Due to its hygroscopic (moisture-sensitive) nature, the container must be kept tightly sealed after opening to prevent degradation from atmospheric moisture. Keep away from strong bases and incompatible materials.
