Description

1-Iodo-2-Naphthol is an organoiodine compound belonging to the naphthol family, serving as a versatile halogenated intermediate. Its value lies in its ability to introduce iodine functionality into complex molecules, enabling the synthesis of specialized materials and active pharmaceutical ingredients. This compound is primarily needed by research institutions and manufacturers in the pharmaceutical, agrochemical, and advanced materials sectors for process development and production.

Application

• Pharmaceutical Intermediate: Key building block in the synthesis of active pharmaceutical ingredients (APIs) and diagnostic agents.
• Agrochemical Synthesis: Used in the production of specialized pesticides and herbicides where iodine substitution is required.
• Material Science Research: Acts as a precursor for organic electronic materials, dyes, and liquid crystals.
• Cross-Coupling Reactions: Valuable substrate in palladium-catalyzed reactions (e.g., Suzuki, Heck) for creating complex biaryl structures.
• Chemical Research & Development: Serves as a standard or reagent in method development and organic synthesis studies.
• Dye and Pigment Manufacturing: Intermediate for producing iodine-containing colorants and photographic chemicals.

Quality Control

Our 1-Iodo-2-Naphthol is produced under a strict quality management system. Each batch undergoes comprehensive analytical testing to ensure identity, purity, and consistency. We provide a detailed Certificate of Analysis (COA) with every shipment, which includes data from techniques such as HPLC, NMR, and IR spectroscopy. Our quality commitment ensures the material meets the stringent requirements for research and industrial synthesis.

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 (store under inert atmosphere), it is recommended to handle under an inert atmosphere (e.g., nitrogen or argon) for long-term storage and to minimize headspace in opened containers.
