Description

4-(2-Oxiranyl)-Benzoic Acid is a versatile aromatic epoxy carboxylic acid derivative, serving as a critical bifunctional building block in advanced organic synthesis. Its unique structure, featuring both a reactive oxirane (epoxide) ring and a carboxylic acid group, enables its use in creating polymers, coatings, and pharmaceutical intermediates with tailored properties. This compound is essential for R&D chemists and production specialists in the pharmaceutical, agrochemical, and specialty polymer industries seeking to introduce cross-linking sites or specific functional handles into their molecular architectures.

Application

• Pharmaceutical Intermediate: Key precursor in the synthesis of active pharmaceutical ingredients (APIs), particularly for molecules requiring epoxy or carboxylic acid functionality for further derivatization.
• Epoxy Resin Modifier: Used as a reactive diluent or curing agent to modify the mechanical, thermal, and adhesive properties of epoxy resin systems for advanced composites and coatings.
• Polymer Cross-Linking Agent: Employed to introduce cross-links into polymer chains, enhancing the durability, chemical resistance, and thermal stability of specialty plastics and elastomers.
• Surface Coating Formulations: Incorporated into high-performance coating formulations to improve adhesion, corrosion resistance, and surface hardness.
• Agrochemical Synthesis: Serves as a building block for synthesizing herbicides, fungicides, and plant growth regulators with specific bioactive profiles.
• Liquid Crystal & Electronic Materials: A valuable monomer for creating polymers used in liquid crystal displays (LCDs) and other electronic applications due to its rigid aromatic core and reactive groups.
• Research & Development: A valuable tool for academic and industrial research in organic chemistry, medicinal chemistry, and materials science for exploring new synthetic pathways.

Quality Control

Every batch of 4-(2-Oxiranyl)-Benzoic Acid is manufactured and tested under a strict quality management system. We ensure compliance with relevant industry standards through rigorous analytical protocols, including HPLC, GC, and NMR, to guarantee identity, purity, and consistency. A comprehensive Certificate of Analysis (COA) detailing all test results is provided with each shipment and is available upon request to support your quality assurance and regulatory needs.

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). 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 incompatible materials such as strong bases and oxidizing agents.
