Description

3-Amino-1-Naphthoic Acid is a versatile 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, makes it a valuable intermediate for constructing complex molecules with tailored properties. This compound is essential for research and production in the pharmaceutical, agrochemical, and specialty dye industries, where it is used to develop active ingredients and functional materials.

Application

• Pharmaceutical Intermediate: Key precursor in the synthesis of non-steroidal anti-inflammatory drugs (NSAIDs), anticancer agents, and other active pharmaceutical ingredients (APIs).
• Agrochemical Synthesis: Building block for creating herbicides, fungicides, and plant growth regulators with specific activity profiles.
• Dye and Pigment Manufacturing: Used in the production of azo dyes, pigments, and optical brighteners due to its naphthalene core and reactive sites.
• Material Science: Intermediate for synthesizing organic semiconductors, liquid crystals, and polymers with enhanced electronic or thermal properties.
• Research & Development: Valuable scaffold in medicinal chemistry for drug discovery and in academic research for exploring new synthetic methodologies.
• Coordination Chemistry: Serves as a ligand for metal-organic frameworks (MOFs) and catalysts, leveraging its chelating ability.

Quality Control

Our 3-Amino-1-Naphthoic Acid is manufactured under strict quality management systems. Each batch undergoes comprehensive analytical testing, including HPLC for purity, IR for identification, and loss on drying for moisture content, to ensure it meets precise customer specifications. Certificates of Analysis (COA) documenting all test results are provided with every shipment.

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