Description

5-Amino-2-Naphthol is a versatile aromatic amine derivative with a fused naphthalene ring structure. This compound serves as a critical intermediate in the synthesis of complex organic molecules, particularly dyes and pigments, due to its reactive amino and phenolic functional groups. It is essential for manufacturers in the fine chemical, pharmaceutical, and specialty colorant industries seeking high-purity building blocks for advanced synthesis.

Application

• Dye and Pigment Intermediate: A key precursor in the manufacture of azo dyes, naphthol AS series pigments, and other high-performance colorants.
• Pharmaceutical Synthesis: Used as a building block for active pharmaceutical ingredients (APIs) and other bioactive molecules.
• Agrochemical Production: Employed in the synthesis of certain herbicides, fungicides, and plant growth regulators.
• Photographic Chemicals: Acts as a component in color couplers for photographic and imaging applications.
• Polymer Additives: Utilized in the production of antioxidants, UV stabilizers, and other functional polymer additives.
• Research & Development: Serves as a standard and reagent in organic chemistry research and analytical laboratories.

Quality Control

Our 5-Amino-2-Naphthol is produced under a strict quality management system. Each batch undergoes comprehensive analytical testing including HPLC for purity, residual solvent analysis, and identification by FT-IR to ensure it meets exacting standards. Certificates of Analysis (COA) detailing all test results are provided with every shipment to guarantee traceability and batch-to-batch consistency for your critical processes.

Storage

Preserve in a tightly closed container, protected from light. Store in a cool, dry, well-ventilated area at a controlled room temperature (15-25°C). Due to its properties of being easily oxidized (store under inert atmosphere) and light-sensitive (store away from light), prolonged exposure to air, moisture, or light should be avoided. Keep away from strong oxidizing agents.
