2-Quinolinol(CAS: 59-31-4)

2-Quinolinol (CAS: 59-31-4) is a crystalline solid with a molecular weight of approximately 135.15 g/mol. It is slightly soluble in water and ethanol but more soluble in organic solvents like methanol and acetone. Chemically, it exhibits basic properties and is a weak base. It is stable under normal conditions but reacts with strong acids to form quinoline salts.

2-Quinolinol is typically synthesized by reduction of 2-quinolinecarboxaldehyde with sodium borohydride. Other methods include the reaction of 2-aminobenzaldehyde with quinoline or the reduction of 2-quinolinecarboxylic acid with lithium aluminum hydride. These methods yield high selectivity and good to excellent yields.

2-Quinolinol is used in the pharmaceutical industry for the synthesis of drugs, in the polymer industry for the production of functional polymers, in the sensor industry for gas sensors, and in the semiconductor industry for photoresists and lithography. It is also used as a chelating agent and in the development of dyes and pigments.

When handling 2-Quinolinol (CAS: 59-31-4), it is important to use appropriate personal protective equipment (PPE), such as gloves and safety goggles. Store the compound in a cool, well-ventilated area away from incompatible materials. Use fume hoods during handling to avoid inhalation. For spills, immediately clean up using appropriate absorbents and dispose of the waste according to local regulations. Always refer to the SDS for detailed safety information.
