Description

3-(4-Aminophenyl)Benzoic Acid is a high-purity aromatic compound that serves as a versatile bifunctional building block in advanced organic synthesis. Its molecular structure, featuring both an aromatic amine and a carboxylic acid group, makes it a critical intermediate for creating complex molecules with tailored properties. This chemical is essential for R&D and production in the pharmaceutical, agrochemical, and specialty polymer industries, where precise molecular architecture is required.

Application

• Pharmaceutical Intermediate: Key precursor in the synthesis of active pharmaceutical ingredients (APIs), particularly for compounds targeting specific receptors or enzymes.
• Agrochemical Synthesis: Used in the development of novel herbicides, fungicides, and plant growth regulators that require an aminophenyl backbone.
• Liquid Crystal & OLED Materials: Acts as a core building block for creating advanced organic electronic materials, including charge-transport layers and emissive compounds.
• Polymer & Resin Modifier: Incorporated into polyamides, polyimides, and epoxy resins to enhance thermal stability, mechanical strength, and adhesion properties.
• Dye & Pigment Manufacturing: Serves as an intermediate for producing azo dyes and high-performance organic pigments with improved lightfastness.
• Cross-coupling Reactions: Valuable substrate in Suzuki, Heck, and other palladium-catalyzed cross-coupling reactions to construct biaryl systems.

Quality Control

Every batch of 3-(4-Aminophenyl)Benzoic Acid is manufactured under a strict quality management system and undergoes comprehensive analytical testing. We ensure compliance with relevant industry standards and provide full traceability. A Certificate of Analysis (COA) detailing purity, identity, and impurity profiles is supplied with each shipment to guarantee batch-to-batch consistency for your critical processes.

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 hygroscopic (moisture-sensitive) nature, the container must be kept tightly sealed after opening to prevent degradation from atmospheric moisture.
