Description

5-Methoxy-2-(trifluoromethyl)benzaldehyde features a trifluoromethyl group at the ortho position and a methoxy substituent at the meta position relative to the aldehyde. This electron-deficient aromatic aldehyde exhibits enhanced stability and solubility in organic solvents, enabling efficient incorporation into synthetic routes for pharmaceutical intermediates and functional materials.

Application

5-Methoxy-2-(trifluoromethyl)benzaldehyde serves as a versatile building block in medicinal chemistry and agrochemical synthesis, enabling efficient construction of substituted heterocycles and functionalized aromatic systems. Its orthogonal reactivity profile—combining a stable aldehyde group with electron-withdrawing trifluoromethyl and electron-donating methoxy substituents—facilitates diverse transformations including nucleophilic additions, Ullmann couplings, and transition-metal-catalyzed cross-couplings. The compound exhibits excellent bench stability and ease of purification, making it well-suited for scalable synthetic workflows.
