Description

2-Propenoic Acid, 3-(4-Phenoxyphenyl)- is a specialty acrylic acid derivative featuring a biphenyl ether backbone, widely recognized for its reactivity as a Michael acceptor and its utility in synthesizing advanced functional materials. Its structural design enables high-performance crosslinking and photochemical stability modulation—making it a critical building block for next-generation polymer systems where precision control over curing kinetics and final film properties is essential. This compound is primarily sought by R&D chemists and formulation scientists in the coatings, adhesives, electronics encapsulation, and photopolymer industries.

Application

• Photocurable resin formulations for UV/EB-curable coatings, inks, and 3D printing resins
• Functional monomer in high-gloss, scratch-resistant automotive clearcoats
• Co-monomer in pressure-sensitive adhesives (PSAs) to enhance cohesive strength and thermal resistance
• Building block for liquid crystal polymer precursors and optical alignment layers
• Intermediate in the synthesis of flame-retardant acrylate oligomers (leveraging the phenoxyphenyl moiety)
• Reactive diluent in low-VOC industrial flooring and electronic encapsulants
• Monomer for biocompatible hydrogel networks requiring controlled degradation profiles

Quality Control

Our products undergo rigorous quality testing to ensure compliance with industry standards. Certificates of Analysis (COA) are available upon request. All batches conform to ACS Reagent Grade specifications for organic acids, including strict limits on residual solvents, heavy metals (<5 ppm), and peroxide-forming impurities. Assay purity is verified via HPLC with UV detection at 254 nm, and identity is confirmed by FT-IR and NMR spectroscopy. We maintain full traceability from synthesis through packaging under ISO 9001-certified quality management systems.

Storage

Preserve in a tightly closed container, protected from light. Store under inert atmosphere (nitrogen or argon) at 15–25°C. Keep away from oxidizing agents and strong bases. Ensure adequate ventilation in storage areas due to potential vapor release. Avoid prolonged exposure to ambient humidity.
