Description

(4-Aminophenoxy)Acetic Acid Methyl Ester is a versatile aromatic amine ester building block of significant importance in fine chemical synthesis. Its bifunctional structure, featuring both a reactive amino group and an ester moiety, makes it a critical intermediate for constructing more complex molecules. This compound is primarily sought after by research institutions and manufacturers in the pharmaceutical and agrochemical sectors for developing active ingredients and advanced materials.

Application

• Pharmaceutical Intermediate: Key building block for the synthesis of active pharmaceutical ingredients (APIs), particularly in the development of compounds with phenoxyacetic acid or aniline-derived structures.
• Agrochemical Synthesis: Used in the production of herbicides, fungicides, and plant growth regulators where its aromatic amine functionality is incorporated into the final product.
• Dye and Pigment Manufacturing: Serves as a precursor for azo dyes and other complex colorants, leveraging the diazotization potential of its primary amino group.
• Polymer Chemistry: Acts as a monomer or chain modifier in the synthesis of specialty polymers, such as polyamides or polyimides, contributing thermal stability and specific functional properties.
• Liquid Crystal and OLED Material Research: Utilized in the development of advanced organic electronic materials due to its rigid aromatic core and modifiable functional groups.
• Cross-coupling Reactions: Employed in palladium-catalyzed reactions (e.g., Buchwald-Hartwig amination) to create complex biaryl ethers and amines.

Quality Control

Our (4-Aminophenoxy)Acetic Acid Methyl Ester is produced under a strict quality management system to ensure batch-to-batch consistency and high purity. Each lot is accompanied by a comprehensive Certificate of Analysis (COA) detailing key parameters such as assay, identity, and impurity profiles. We support custom synthesis and purity grades (including pharmaceutical intermediates grade) to meet specific project requirements. Certificates of Analysis (COA) are 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 light-sensitive and easily oxidized nature, it is recommended to store the product under an inert atmosphere (e.g., nitrogen or argon) for long-term preservation. Keep away from strong oxidizing agents, strong acids, and strong bases.
