Description

1,3-Phenylenediacetic Acid is a high-purity aromatic dicarboxylic acid derivative, serving as a critical building block in advanced organic synthesis. Its bifunctional structure, featuring two reactive acetic acid groups on a meta-substituted benzene ring, makes it an invaluable intermediate for creating complex molecules with precise spatial configurations. This compound is essential for researchers and manufacturers in the pharmaceutical, agrochemical, and specialty polymer industries who require reliable, high-quality intermediates for developing active ingredients and functional materials.

Application

• Pharmaceutical Intermediate: Key precursor in the synthesis of active pharmaceutical ingredients (APIs), particularly for compounds requiring a meta-substituted aromatic core with carboxylic acid functionality.
• Ligand Synthesis: Used to prepare chelating agents and ligands for metal catalysis and coordination chemistry applications.
• Polymer Chemistry: Serves as a monomer or chain extender in the production of specialty polyamides, polyesters, and other high-performance polymers.
• Agrochemical Synthesis: Intermediate in the manufacture of herbicides, fungicides, and plant growth regulators.
• Dye and Pigment Manufacturing: Building block for synthesizing complex organic dyes and pigments.
• Research & Development: Valuable reagent in academic and industrial R&D for exploring new chemical entities and material properties.
• Cross-linking Agent: Potential use in creating cross-linked networks for resins and coatings due to its diacid structure.

Quality Control

Our 1,3-Phenylenediacetic Acid is manufactured under a strict quality management system. Each batch undergoes comprehensive analytical testing, including HPLC for purity and identity confirmation by FT-IR and NMR, to ensure it meets the high standards required for synthetic applications. A Certificate of Analysis (COA) detailing all test results is provided with every shipment. We support compliance with global regulatory frameworks, including REACH.

Storage

Preserve in a tightly closed container, protected from light. Store in a cool, dry, and well-ventilated area at room temperature (15-25°C). Due to its hygroscopic nature, the container must be kept tightly sealed to prevent moisture absorption, which can affect product quality. Keep away from incompatible materials such as strong bases and oxidizing agents.
