Basic Information
Product Name: 8-Hydroxyquinoline
CAS Number: 148-24-3
Alias: Oxine, 8-Quinolinol
Molecular Formula: C9H7NO
Molecular Weight: 145.16 g/mol
IUPAC Name: quinolin-8-ol
Structural Information
- Structure Type: Aromatic heterocyclic compound, quinoline derivative
- Structural Features: Consists of fused benzene and pyridine rings, with a hydroxyl group attached at the 8-position. It has strong chelating ability with various metal ions due to the adjacent hydroxyl and nitrogen atom.
Physical & Chemical Properties
- Appearance: White to pale yellow crystalline powder
- Odor: Slight characteristic odor
- Melting Point: 75–76 °C
- Boiling Point: 267 °C
- Solubility: Slightly soluble in cold water; soluble in hot water, ethanol, ether, chloroform and dilute acid solutions
- Stability: Stable under normal sealed conditions. Gradually darkens upon long exposure to light and air. Reacts with metal ions, strong oxidants and concentrated alkalis.
Synthesis & Applications
Synthesis Method
Prepared by sulfonation and alkali fusion of quinoline, followed by acidification and recrystallization to obtain high-purity finished product.
Main Applications
- Analytical Chemistry: Classic metal chelating agent and indicator for qualitative and quantitative detection of metal ions.
- Pharmaceutical Industry: Intermediate for synthesizing antibacterial, antimalarial and disinfectant drugs.
- Preservative & Fungicide: Used as bactericide, mildew inhibitor in cosmetics, coatings and textile products.
- Organic Synthesis: Important raw material for preparing quinoline derivatives and fine chemicals.
