Description

4-(2-Methacryloxy-Ethyl-1-Oxy)Benzoic Acid is a specialized methacrylate-functionalized benzoic acid derivative, serving as a critical building block in advanced polymer synthesis. This compound matters for its ability to introduce both polymerizable methacrylate groups and carboxylic acid functionality into a single monomer, enabling the creation of materials with tailored surface properties and reactivity. It is primarily needed by manufacturers in the photopolymer, dental materials, and specialty adhesive industries seeking to develop high-performance, cross-linkable resins and functional coatings.

Application

• Photopolymer and UV-Curable Resins: A key monomer for formulating advanced photoresists, printing plates, and UV-curable coatings and inks.
• Dental Restorative Materials: Used in the synthesis of adhesive monomers and resin composites for dental bonding and fillings.
• Functional Polymer Synthesis: Serves as a reactive intermediate for creating polymers with pendant carboxylic acid groups for ion-exchange, adhesion promotion, or further chemical modification.
• Surface Modification and Coatings: Employed to graft polymer chains onto surfaces, enhancing biocompatibility, wettability, or specific binding characteristics.
• Cross-linking Agent: Acts as a difunctional cross-linker in acrylic and methacrylic polymer systems to improve mechanical strength and chemical resistance.
• Biomedical Hydrogels: Utilized in the development of pH-responsive or functionalizable hydrogels for drug delivery and tissue engineering applications.

Quality Control

Our 4-(2-Methacryloxy-Ethyl-1-Oxy)Benzoic Acid is produced under a strict quality management system. Each batch undergoes rigorous analytical testing, including HPLC for purity and identity confirmation, to ensure it meets precise specifications for advanced synthesis. Certificates of Analysis (COA) documenting assay, impurity profile, and physical characteristics are provided with every shipment.

Storage

Preserve in a tightly closed container, protected from light. Store in a cool, dry, and well-ventilated area at a controlled room temperature (15-25°C). This material is light-sensitive and should be handled under an inert atmosphere when possible to prevent premature polymerization. Keep away from heat and incompatible materials such as strong oxidizers, bases, and polymerization initiators.
