Description

3-Aminophthalic Acid is a versatile aromatic dicarboxylic acid derivative that serves as a critical building block in advanced organic synthesis. Its bifunctional nature, featuring both an amine and two carboxylic acid groups, makes it a valuable precursor for creating complex heterocyclic compounds and functional materials. This high-purity intermediate is essential for research and production in the pharmaceutical, agrochemical, and specialty chemical industries, where it is used to develop active ingredients and sophisticated molecular architectures.

Application

• Pharmaceutical Intermediate: Key precursor in the synthesis of various active pharmaceutical ingredients (APIs) and diagnostic agents.
• Agrochemical Synthesis: Building block for developing novel herbicides, fungicides, and plant growth regulators.
• Dye and Pigment Manufacturing: Used in the production of specialized azo dyes and fluorescent pigments.
• Ligand and Chelating Agent: Serves as a starting material for synthesizing complexing agents and metal-organic frameworks (MOFs).
• Polymer Chemistry: Monomer for the creation of polyamides, polyimides, and other high-performance polymers.
• Research & Development: Fundamental reagent in academic and industrial R&D for exploring new chemical entities and reaction pathways.

Quality Control

Our 3-Aminophthalic Acid is manufactured under a strict quality management system. Every batch undergoes comprehensive analytical testing to ensure it meets the high standards required for industrial and research applications. A Certificate of Analysis (COA) detailing purity, identity, and impurity profiles is provided with each shipment, ensuring full traceability and compliance.

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 nature, the container must be kept tightly sealed after opening to prevent moisture absorption, which can affect product stability and performance.
