Industrial Applications of 8-Quinolinecarboxylic acid
| Industry | Application | Process |
|---|---|---|
| Pharmaceuticals | Antibacterial drug intermediate for synthesizing quinolone antibiotics (e.g., cinoxacin) | Converted to acyl chloride via reaction with thionyl chloride, followed by condensation with amines |
| Agrochemicals | Intermediate for fungicides and insecticides | Participates in heterocyclic coupling reactions to construct quinoline-containing active molecules |
| Materials Science | Ligand for metal–organic frameworks (MOFs), used in gas adsorption and separation materials | Acts as a bidentate chelating ligand coordinating with transition metals (e.g., Zn²⁺, Cu²⁺) to assemble MOFs |
| Analytical Chemistry | Fluorescent probe and reagent for metal ion detection | Forms stable fluorescent complexes with Al³⁺, Mg²⁺, etc., for colorimetric/fluorometric analysis |
Manufacturing Quality Control of 8-Quinolinecarboxylic acid
| Detection Item | Common Analytical Method | Method Overview |
|---|---|---|
| Assay (Purity) | HPLC with UV detection | Quantitative determination based on peak area comparison against a certified reference standard using reversed-phase chromatography. |
| Loss on Drying (LOD) | Gravimetric thermogravimetry | Mass loss measured after drying at 105 °C to constant weight, indicating volatile impurities and residual solvents. |
| Residue on Ignition (Sulfated Ash) | Gravimetric sulfated ash assay | Inorganic residue quantified after high-temperature incineration with sulfuric acid treatment. |
| Heavy Metals (as Pb) | ICP-OES or AAS | Total heavy metal content determined by atomic emission or absorption spectroscopy after acid digestion. |
| Chloride Impurity | Potentiometric titration with AgNO₃ | Quantification of chloride ions via precipitation titration using silver nitrate and a silver indicator electrode. |
| Related Substances | HPLC with gradient elution and UV detection | Separation and quantification of structurally similar impurities using optimized reversed-phase chromatographic conditions. |
| Melting Point | Capillary melting point apparatus | Thermal transition temperature range determined by controlled heating of crystalline sample in capillary tube. |
| Water Content (KF) | Karl Fischer coulometric titration | Electrochemical quantification of water content based on iodine generation and stoichiometric reaction with water. |
| pH of Aqueous Suspension | pH meter measurement | Acidity/basicity assessed by measuring the pH of a defined suspension (e.g., 1% w/v) in purified water. |
| Solvent Residues (e.g., MeOH, EtOAc) | GC-FID | Identification and quantification of residual organic solvents using gas chromatography with flame ionization detection. |
| Particle Size Distribution | Laser diffraction analysis | Determination of particle size distribution by measuring angular variation in laser light scattering intensity. |
| Specific Optical Rotation | Polarimetry | Measurement of rotation angle of plane-polarized light induced by chiral molecules in solution. |
| Microbial Contamination | Membrane filtration and plate count | Quantification of aerobic microorganisms per pharmacopeial methods (e.g., USP <61>). |
