Description

5-Amino-1-Naphthol is a versatile aromatic amine derivative of naphthalene, serving as a critical intermediate in the synthesis of complex organic molecules. Its bifunctional nature, containing both an amino and a hydroxyl group, makes it a valuable building block for creating dyes, pigments, and advanced pharmaceutical compounds. This high-purity intermediate is essential for manufacturers in the fine chemical, agrochemical, and specialty dye industries seeking reliable and consistent raw materials for their production processes.

Application

• Dye and Pigment Intermediate: A key precursor in the synthesis of azo dyes, naphthol AS series pigments, and other colorants for textiles, inks, and plastics.
• Pharmaceutical Synthesis: Used as a building block in the manufacture of certain active pharmaceutical ingredients (APIs) and diagnostic agents.
• Agrochemical Production: Employed in the synthesis of herbicides, pesticides, and plant growth regulators.
• Photographic Chemicals: Acts as a developing agent or a component in photographic developer solutions.
• Polymer Stabilizers: Can be utilized in the production of antioxidants and UV stabilizers for polymers and rubbers.
• Research & Development: Serves as a standard or reagent in organic chemistry research and analytical laboratories.
• Corrosion Inhibitors: A component in formulations designed to protect metals from oxidation and corrosion.

Quality Control

Our 5-Amino-1-Naphthol is manufactured under strict quality management systems to ensure batch-to-batch consistency and high purity. Each lot undergoes comprehensive analytical testing, including HPLC for assay and impurity profiling, to meet exacting customer specifications. A Certificate of Analysis (COA) detailing all test results is provided with every shipment, ensuring full traceability and compliance with your quality assurance protocols.

Storage

Preserve in a tightly closed container, protected from light. Store in a cool, dry, well-ventilated area at room temperature (15-25°C). Due to its sensitivity to oxidation, it is recommended to store under an inert atmosphere for long-term preservation. Keep away from strong oxidizing agents, acids, and bases.
