8-Hydroxyquinoline[2]
Overview
8-Hydroxyquinoline is an organic compound with the molecular formula C9H7NO. It is widely used in various industrial and pharmaceutical applications due to its chelating and antimicrobial properties. The compound is a derivative of quinoline and is known for its ability to form stable complexes with metal ions. First synthesized in the late 19th century, 8-Hydroxyquinoline has since become a critical reagent in analytical chemistry, metal extraction, and as a precursor in the synthesis of other chemicals. Its versatility and effectiveness make it a staple in many B2B chemical supply chains.
Physical and Chemical Properties
8-Hydroxyquinoline is a white to pale yellow crystalline powder with a distinct odor. It has a melting point of 76-78°C and a boiling point of 267°C. The compound is soluble in organic solvents like ethanol and acetone but only slightly soluble in water. One of its key chemical properties is its ability to act as a chelating agent, forming stable complexes with metal ions such as iron, copper, and aluminum. This property is exploited in various industrial processes, including metal extraction and corrosion inhibition. Additionally, 8-Hydroxyquinoline exhibits fluorescent properties, making it useful in analytical applications.
Main Applications
8-Hydroxyquinoline is used in a wide range of applications. In the pharmaceutical industry, it serves as an intermediate in the synthesis of drugs and as an antimicrobial agent. Its metal-chelating properties are utilized in metal extraction processes, particularly in hydrometallurgy. In agriculture, it is used as a fungicide and pesticide. The compound is also employed as an analytical reagent in laboratories for the detection and quantification of metal ions. Its fluorescent properties make it valuable in biochemical assays and imaging techniques.
Safety and Storage
8-Hydroxyquinoline is classified as harmful if swallowed or inhaled. Proper personal protective equipment (PPE), including gloves and goggles, should be worn when handling the compound. Adequate ventilation is essential to avoid inhalation of dust or vapors. The compound should be stored in a cool, dry place away from light and moisture to prevent degradation. Containers should be tightly sealed to avoid contamination and exposure to air. In case of spillage, absorb the material with an inert substance and dispose of it according to local regulations.
B2B Procurement Guide
When procuring 8-Hydroxyquinoline, B2B buyers should verify the purity and CAS number (148-24-3) to ensure they are receiving the correct product. Certificates of analysis (CoA) from suppliers can provide assurance of quality. Bulk orders typically offer cost savings, so buyers should consider their long-term needs. It is also advisable to source from reputable suppliers with a track record of reliability and compliance with safety standards. Prices commonly range from $50 to $150 per kg, depending on purity and order volume.
