Description
2,3-Quinolinedicarboxylic acid features a rigid, electron-deficient quinoline core paired with two carboxylic acid groups at the 2- and 3-positions. This structural motif enables strong coordination to metal ions in supramolecular assemblies and facilitates incorporation into metal-organic frameworks. The molecule exhibits enhanced solubility in polar solvents compared to unsubstituted quinolines, simplifying handling in aqueous or mixed solvent systems.
Application
2,3-Quinolinedicarboxylic acid serves as a versatile building block in heterocyclic synthesis, enabling efficient access to quinoline-based scaffolds through established coupling and cyclization protocols. Its dual carboxylic acid functionality supports diverse derivatization—particularly in metal coordination, peptide coupling, and polymer synthesis—while maintaining bench stability and ease of purification. The molecule functions effectively in the construction of bioactive compounds and functional materials, offering predictable reactivity in standard organic transformations.
