8-Hydroxyquinoline (8-HQ) (CAS 148-24-3), also known as Oxine, is a versatile heterocyclic chelating agent. In the Elemental Derivatives, Agrochemical, and Pharmaceutical hierarchies, 8-quinolinol serves as a foundational building block for synthesizing a broad spectrum of antimicrobial and antifungal agents. Oxyquinoline's unique ability to form stable coordination complexes with metal ions - particularly copper, zinc, and iron - makes it an indispensable intermediate in the production of crop protection chemicals and antiseptic therapeutics. Source High-Purity 8-Hydroxyquinoline, a leading global manufacturer and wholesale supplier of 8-HQ. Our product serves as a critical quinoline intermediate for the synthesis of major fungicides such as 8-Hydroxyquinoline sulfate and Copper Quinolate. For Pharmaceutical CDMOs, our 8-HQ is an essential precursor for the production of halogenated derivatives like Iodoquinol and Clioquinol, used extensively in anti-amoebic and antiseptic treatments. As an authoritative 8-Quinolinol manufacturer, we ensure our bulk material meets stringent international quality standards, providing the high-titer chelation performance required for metallurgy chemicals and analytical reagents. Whether you are formulating advanced crop protection chemicals or high-purity API building blocks, our 8-Hydroxyquinoline delivers consistent bio-efficacy and reliable worldwide lead times.

Production of Quinolate fungicides. 8-HQ reacts with copper salts to form Copper-8-quinolinolate, a powerful seed protectant and wood preservative that prevents fungal decay
Primary APIs for intestinal anti-infectives. 8-HQ Halogenation ring results in potent medicines like Cloxiquine and Halquinols, used in both human and veterinary medicine to treat skin infections and gastrointestinal distress
Precipitating agent and extraction reagent in the separation of metals such as aluminum, magnesium, and zinc. Forms insoluble metal-oxinate complexes is vital for Specialty Metal Salts & Reagents.
Stable under normal temperatures; however, it is light-sensitive and can darken over time if exposed to air and UV light
Store in a cool, dry, well-ventilated area
Keep containers tightly closed and protected from light
Recommended storage is 15°C to 25°C
Because of its unique chelation properties. Once it forms a complex with copper or zinc, it becomes highly insoluble in water but retains massive bio-potency against fungi, allowing the treatment to remain on the seed even in damp soil conditions.
We monitor for residual Quinoline and Phenol impurities via HPLC. Our process ensures a purity level of ≥ 99.5%, which is critical for CDMOs who use 8-HQ as a starting material for validated API synthesis to prevent downstream by-products.
Yes. 8-HQ is a "General Functional Reagent" in metallurgy used to extract and refine various metal elements by forming solvent-extractable complexes, making it essential for Rare Earth Metal processing.
