Quinoline CAS 91-22-5 Purity >99.0% (GC) Factory

Quinoline (CAS: 91-22-5) is a heterocyclic aromatic organic compound with the chemical formula C9H7N. Quinoline derivatives are prevalent in a variety of pharmacologically active synthetic and natural compounds. Quinolines have antiseptic, antipyretic, and antiperiodic properties and are used as antimalarials and for preparing other antimalarial drugs. Quinoline and its derivatives are widely used as fungicides, biocides, antibiotics, alkaloids, dyes, rubber chemicals, and flavoring agents. Additional industrial applications include their Application use as corrosion inhibitors, preservatives, and as solvents for resins and terpenes, and in transition-metal complex catalysis for uniform polymerization and luminescence chemistry. They are also used in manufacturing oil soluble dyes, food colorants, pharmaceuticals, pH indicators and other organic compounds. Quinoline is a catabolite of tryptophan, a fundamental structure in some antihypertensive agents such as the peripheral vasodilators prazosin and doxazosin. Quinoline used in the preparation of nicotinic acid and hydroxy quinoline drugs, cyanine blue pigment and photosensitive pigment, rubber accelerator and pesticide products such as quinoline ketone. Used as organic reagents, alkaline condensation agent and solvent. Used as analytical reagents, solvents, but also for the separation of vanadate and arsenate. Making the arm, but also can be used as a preservative in acid, solvent, etc., for the production of nicotinic acid and 8-Hydroxylquinoline drug pharmaceutical industry, for preparing cyanine pigments and photosensitive pigment printing and dyeing industry, used for accelerator rubber industry, agriculture for the production of 8-Hydroxyquinoline copper pesticide. Quinoline acts as a precursor to 8-Hydroxyquinoline, Hydroxyquinoline Sulfate and Niacin.

Quinoline is a hygroscopic liquid with characteristic odour. On exposure to light, it turns brown in colour. Quinoline decomposes on heating, and on burning produces toxic fumes including nitrogen oxides. Quinoline reacts with strong oxidants, acids, and anhydrides. Quinoline is only slightly soluble in cold water but dissolves readily in hot water and most organic solvents. Quinoline is combustible. It gives off irritating or toxic fumes (or gases) in a fire. Quinoline is incompatible with strong acids, oxidisers, dinitrogen tetroxide, linseed oil, thionyl chloride, maleic anhydride, and perchromates and reacts violently with most incompatibles.
