7-Chloroquinoline-3-carboxylic acid(CAS: 892874-49-6)

7-Chloroquinoline-3-carboxylic acid is a white crystalline solid with a molecular weight of approximately 213.01 g/mol. It is slightly soluble in water and more soluble in organic solvents like ethanol and acetone. Chemically, it is moderately reactive, showing basic properties due to the presence of the carboxylic acid group. It can react with bases to form salts and with certain reagents to undergo substitution reactions.

7-Chloroquinoline-3-carboxylic acid is typically synthesized by the condensation of 7-chloroquinoline with acetic anhydride in the presence of a catalyst such as sulfuric acid. The reaction is carried out under mild conditions, and the yield is usually around 70-80%. The product is purified by recrystallization from an appropriate solvent.

7-Chloroquinoline-3-carboxylic acid is used in various industries. It is a key intermediate in the synthesis of pharmaceuticals, particularly for the development of antimalarial drugs. Additionally, it is used in the production of dyes, pigments, and other organic compounds. Due to its chemical reactivity, it also finds applications in sensor technologies and as a precursor in semiconductor manufacturing.

When handling 7-Chloroquinoline-3-carboxylic acid, appropriate personal protective equipment (PPE) should be worn, including gloves, safety goggles, and a lab coat. The compound should be used in a well-ventilated area or a fume hood to minimize inhalation risks. Spills should be handled carefully, and the area should be ventilated until the spill is cleaned up. It is recommended to follow the safety data sheet (SDS) for detailed handling instructions and emergency procedures.
