Description

2-(4-Aminophenoxy)Benzene Carboxylic Acid is a versatile aromatic compound featuring both carboxylic acid and primary amine functional groups on a diphenyl ether scaffold. This bifunctional nature makes it a valuable intermediate for synthesizing complex molecules, particularly in the pharmaceutical and advanced materials sectors. It is essential for researchers and manufacturers developing high-performance polymers, liquid crystals, and active pharmaceutical ingredients (APIs).

Application

• Pharmaceutical Intermediate: A key building block for the synthesis of novel drug candidates, especially those targeting central nervous system (CNS) disorders and anti-inflammatory applications.
• Polymer & Resin Synthesis: Used in the production of high-temperature resistant polyamides, polyimides, and epoxy curing agents, contributing to materials with enhanced thermal and mechanical properties.
• Liquid Crystal Materials: Serves as a core component in the manufacture of advanced liquid crystal displays (LCDs) and optical materials due to its rigid, planar structure.
• Dye & Pigment Manufacturing: Acts as a precursor for azo dyes and organic pigments, providing improved color fastness and stability.
• Agrochemical Synthesis: Employed in the development of new-generation herbicides and plant growth regulators.
• Research & Development: A crucial reagent in organic chemistry laboratories for coupling reactions and the creation of specialized chemical libraries.

Quality Control

Every batch of 2-(4-Aminophenoxy)Benzene Carboxylic Acid is produced under a strict quality management system. We employ advanced analytical techniques, including HPLC and NMR, to ensure high purity and consistent batch-to-batch quality. A comprehensive Certificate of Analysis (COA) detailing identity, purity, and impurity profiles is provided with each shipment to support your quality assurance and regulatory compliance needs.

Storage

Preserve in a tightly closed container, protected from light. Store in a cool, dry, and well-ventilated place at a controlled room temperature (15-25°C). Due to its sensitivity to oxidation, 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.
