Description

6-Chloro-2-Hydroxyquinoline-3-Carbaldehyde is a versatile and highly functionalized quinoline derivative, serving as a critical synthetic intermediate in advanced organic chemistry. Its unique molecular scaffold, featuring both aldehyde and hydroxyl groups on a chlorinated quinoline core, makes it an indispensable building block for constructing complex heterocyclic systems. This compound is primarily sought after by research institutions and pharmaceutical companies engaged in the development of novel active pharmaceutical ingredients (APIs), agrochemicals, and specialty dyes.

Application

• Pharmaceutical Intermediate: A key precursor in the synthesis of quinoline-based drug candidates with potential anti-malarial, anti-cancer, or anti-inflammatory properties.
• Agrochemical Research: Used to develop novel fungicides, herbicides, or plant growth regulators that leverage the bioactive quinoline structure.
• Material Science & Dyes: Acts as a building block for creating organic semiconductors, fluorescent probes, or complex dye molecules due to its conjugated system.
• Coordination Chemistry & Ligand Synthesis: The aldehyde and hydroxyl groups provide sites for condensation reactions to form Schiff base ligands for metal complexes.
• Academic & R&D Laboratories: Employed in methodological studies and the discovery of new heterocyclic compounds and reaction pathways.

Quality Control

Our 6-Chloro-2-Hydroxyquinoline-3-Carbaldehyde is manufactured under strict quality management protocols. Each batch undergoes comprehensive analytical testing, including HPLC for purity, NMR and IR for structural confirmation, and tests for residual solvents and heavy metals, to ensure it meets the high standards required for research and development. A detailed Certificate of Analysis (COA) is provided with every shipment to guarantee traceability, consistency, and reliability for your critical synthesis work.

Storage

Preserve in a tightly closed container, protected from light. Store in a cool, dry, and well-ventilated place at room temperature (15-25°C). Due to its light-sensitive nature and propensity to be easily oxidized, it is recommended to handle under an inert atmosphere for long-term storage and to minimize exposure to air and moisture.
