6-Methoxy-2-quinolinecarboxylic acid(CAS: 75433-99-7)

6-Methoxy-2-quinolinecarboxylic acid is a crystalline solid with a molecular weight of approximately 223.18 g/mol. It has a low water solubility and is moderately soluble in organic solvents like methanol and ethanol. Chemically, it is relatively stable under neutral and basic conditions but can react with strong acids. It is known for its weak acidity and can form complexes with certain metal ions.

6-Methoxy-2-quinolinecarboxylic acid is typically synthesized through a condensation reaction between 2-quinolinecarboxylic acid and methanol in the presence of an acid catalyst such as sulfuric acid. The reaction involves the formation of an ester bond between the carboxylic acid and methanol. The yield is usually around 85-90%, with the product purified by recrystallization from ethanol.

6-Methoxy-2-quinolinecarboxylic acid is primarily used in the pharmaceutical industry as a precursor for the synthesis of various drug candidates. It also finds applications in the production of certain organic pigments and dyes. Additionally, it is used in the development of sensor materials and in some electronic applications due to its structural properties.

When handling 6-Methoxy-2-quinolinecarboxylic acid, it is important to wear appropriate personal protective equipment (PPE) such as gloves and safety goggles. The compound should be stored in a cool, dry place away from direct sunlight. In case of a spill, it should be cleaned up using appropriate containment measures, and the area should be well-ventilated. Always refer to the Safety Data Sheet (SDS) for detailed handling and emergency procedures.
