Description

1-Aminonaphthalene-2-Carboxylic Acid is a high-purity aromatic amine-carboxylic acid derivative, serving as a critical building block in advanced organic synthesis. Its bifunctional structure, featuring both an amino and a carboxylic acid group on the naphthalene ring, makes it a versatile intermediate for creating complex molecules. This compound is essential for research and production in the pharmaceutical, agrochemical, and specialty dye industries, where precise molecular architecture is required.

Application

• Pharmaceutical Intermediate: Key precursor in the synthesis of active pharmaceutical ingredients (APIs), particularly for compounds with naphthalene-based scaffolds.
• Agrochemical Synthesis: Used in the development of advanced herbicides, fungicides, and plant growth regulators.
• Dye and Pigment Manufacturing: Serves as a core structure for producing high-performance, light-fast azo dyes and organic pigments.
• Material Science Research: Building block for organic semiconductors, metal-organic frameworks (MOFs), and functional polymers.
• Chemical Research & Development: Valuable reagent for academic and industrial R&D in organic and medicinal chemistry.
• Ligand Synthesis: Used to create chelating agents and complexing ligands for catalysis and metal ion separation.

Quality Control

Our 1-Aminonaphthalene-2-Carboxylic Acid is manufactured under strict quality management systems. Every batch undergoes comprehensive analytical testing, including HPLC for purity and identity confirmation, to ensure it meets the stringent requirements of our global clientele. A detailed Certificate of Analysis (COA) is provided with each shipment, documenting key parameters such as assay, impurity profile, and physical characteristics.

Storage

Preserve in a tightly closed container, protected from light. Store in a cool, dry, well-ventilated place at a controlled room temperature (15-25°C). Due to its light-sensitive and easily oxidized nature, it is recommended to store the material under an inert atmosphere (e.g., nitrogen or argon) for long-term preservation and to minimize degradation.
