Description

3,3'-[5-(Hydroxymethyl)-1,3-Phenylene]Bis(2-Propenoic Acid) Diethyl Ester is a high-purity, multifunctional organic building block with a reactive hydroxymethyl group and two acrylate ester functionalities. This compound matters as a versatile monomer or cross-linking agent, enabling the synthesis of advanced polymers with tailored properties such as enhanced adhesion, cross-link density, and chemical resistance. It is primarily needed by R&D chemists and process engineers in the pharmaceutical, advanced material science, and specialty polymer industries for developing novel coatings, resins, and pharmaceutical intermediates.

Application

• Pharmaceutical Intermediate: Serves as a key synthon in the development of novel active pharmaceutical ingredients (APIs) and prodrugs, leveraging its ester and hydroxymethyl groups for further functionalization.
• UV-Curable Resins & Coatings: Acts as a reactive diluent or cross-linker in acrylate-based formulations for inks, adhesives, and protective coatings that cure rapidly under UV light.
• Dendrimer and Hyperbranched Polymer Synthesis: Utilized as an ABx-type monomer to construct complex, three-dimensional macromolecular architectures with precise functionality.
• Thermoset Polymers: Incorporated into polyester or acrylic resin systems to improve hardness, thermal stability, and chemical resistance in composite materials.
• Bioconjugation and Linker Chemistry: The hydroxymethyl group provides a handle for attaching biomolecules, dyes, or other functional units in diagnostic or drug delivery system development.
• Specialty Adhesives: Enhances performance characteristics in high-strength, industrial-grade adhesive formulations.

Quality Control

Every batch of 3,3'-[5-(Hydroxymethyl)-1,3-Phenylene]Bis(2-Propenoic Acid) Diethyl Ester is manufactured and tested under a strict quality management system. We provide comprehensive analytical data to ensure the product meets the high-purity standards required for research and industrial synthesis. 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 room temperature (15-25°C). Due to its hygroscopic (moisture-sensitive) nature, the container must be kept sealed under an inert atmosphere (e.g., nitrogen or argon) after opening to prevent degradation. Keep away from heat, sparks, and open flame.
