Quinoline, identified by its CAS number 91-22-5, is a fundamental heterocyclic aromatic organic compound with widespread utility across various industries. NINGBO INNO PHARMCHEM CO.,LTD. is a leading supplier of high-purity Quinoline, ensuring that industries have access to a reliable source for this critical chemical intermediate. This article delves into its key properties, diverse applications, and essential safety guidelines.

Physical and Chemical Properties: Quinoline typically presents as a colorless to light yellow, clear liquid. It possesses a characteristic strong odor and a high boiling point of approximately 237-239°C. With a density around 1.09 g/cm³, it is slightly denser than water and has limited solubility in water but is miscible with many organic solvents. Chemically, Quinoline is a weak base and is stable under normal storage conditions, though it may discolor upon exposure to light and is hygroscopic, requiring protection from moisture. Its purity, often exceeding 98%, is vital for its performance in downstream applications.

Industrial Applications: The versatility of Quinoline is evident in its extensive applications. It is a crucial organic intermediate used in the synthesis of pharmaceuticals, including antimalarial drugs and cardiovascular agents. In the dye industry, it serves as a precursor for vibrant pigments and photosensitive compounds. The agricultural sector utilizes Quinoline as a pesticide precursor and in the formulation of plant growth regulators. Furthermore, its role as a rubber accelerator enhances the properties of rubber products, and it also finds use as an industrial solvent.

Safety and Handling: Quinoline is classified as a hazardous substance and requires careful handling. It is toxic if swallowed, harmful if in contact with skin, and can cause skin and serious eye irritation. Long-term exposure may pose additional risks, including suspected mutagenicity and carcinogenicity. Therefore, proper personal protective equipment, such as gloves, safety goggles, and protective clothing, is essential when handling Quinoline. Storage should be in a cool, dry, well-ventilated area, away from incompatible materials like strong acids and oxidizing agents. Strict adherence to safety data sheets (SDS) and local regulations is paramount to ensure safe use and prevent environmental release.
