Description

8-Chloronaphthalene-1-Carboxaldehyde is a versatile and high-purity aromatic aldehyde building block, essential for advanced organic synthesis. Its core value lies in its unique halogenated naphthalene structure, which enables the introduction of both aldehyde and chloro functional groups into complex molecular frameworks. This compound is critically needed by research chemists and process development scientists in the pharmaceutical, agrochemical, and material science industries for creating novel active ingredients and functional materials.

Application

• Pharmaceutical Intermediate: Serves as a key precursor in the synthesis of novel drug candidates, particularly for molecules targeting central nervous system (CNS) disorders and anti-inflammatory applications.
• Agrochemical Synthesis: Used in the development of new-generation herbicides, fungicides, and plant growth regulators, leveraging its halogenated aromatic core.
• Organic Light-Emitting Diodes (OLEDs): Acts as a building block for electron-transport materials and host molecules in display and lighting technologies.
• Ligand and Catalyst Development: Employed in the preparation of specialized chiral ligands and metal-organic frameworks (MOFs) for asymmetric catalysis.
• Dye and Pigment Manufacturing: Functions as an intermediate for producing high-performance, color-fast naphthalene-based dyes and pigments.
• Academic and R&D: A valuable reagent for methodological studies in cross-coupling reactions, formylation chemistry, and heterocycle formation.

Quality Control

Our 8-Chloronaphthalene-1-Carboxaldehyde is manufactured under strict quality management systems. Each batch undergoes rigorous analytical testing, including HPLC, GC, and NMR, to ensure high purity and batch-to-batch consistency. A comprehensive Certificate of Analysis (COA) detailing identity, purity, and impurity profiles is provided with every shipment to support your quality assurance and regulatory compliance needs.

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 sensitivity to oxidation, it is recommended to store under an inert atmosphere (e.g., nitrogen or argon) for long-term preservation. Keep away from heat, sparks, and open flames.
