Description

3,7-Dihydroxy-2-Naphthoic Acid is a high-purity naphthalene derivative that serves as a critical building block in advanced organic synthesis. Its bifunctional structure, featuring both carboxylic acid and phenolic hydroxyl groups, makes it a versatile intermediate for creating complex molecules with specific optical and chemical properties. This compound is essential for R&D 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 intermediate for producing high-performance, light-fast azo dyes and organic pigments.
• Liquid Crystal & OLED Materials: A valuable starting material for synthesizing organic semiconductors and charge-transport materials used in electronic displays.
• Chemical Research & Development: Employed in academic and industrial labs for novel heterocyclic compound synthesis and material science projects.
• Coordination Chemistry: Acts as a chelating ligand for metal ions in catalyst design and metal-organic framework (MOF) construction.

Quality Control

Our 3,7-Dihydroxy-2-Naphthoic Acid is manufactured under a strict quality management system. Each batch is subjected to comprehensive analytical testing, including HPLC for purity and identity confirmation via FT-IR and NMR. We provide full traceability and Certificates of Analysis (COA) are supplied with every shipment to ensure compliance with your specific project requirements.

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 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.
