3-Formyl-4-methoxybenzoic acid features a formyl group at the meta position relative to the carboxylic acid, paired with a para-methoxy substituent. This electron-rich aromatic scaffold enables direct coupling in cross-coupling reactions and serves as a key building block for bioactive heterocycles. The molecule exhibits enhanced solubility in polar organic solvents and maintains stability under standard bench conditions.
3-Formyl-4-methoxybenzoic acid serves as a versatile building block in medicinal chemistry, enabling direct functionalization at both the aldehyde and carboxylic acid termini. Its orthogonal reactivity facilitates efficient coupling, amidation, or reductive amination workflows, while the methoxy group enhances solubility and modulates electronic properties. Bench-stable and readily purified by recrystallization, it functions reliably in multi-step syntheses of heterocyclic scaffolds and bioactive molecule intermediates.
