3,4-Dimethoxybenzaldehyde（Cat No.:R049259）, also known as veratraldehyde, is an aromatic aldehyde with the molecular formula C₉H₁₀O₃. It features a benzene ring substituted with two methoxy groups at the 3 and 4 positions and an aldehyde group at position 1. This pale yellow solid has a sweet, vanilla-like odor and is used as a flavoring agent, fragrance component, and intermediate in organic synthesis. It is commonly utilized in the production of pharmaceuticals, agrochemicals, and dyes. The electron-donating methoxy groups enhance the reactivity of the aldehyde in electrophilic aromatic substitution and condensation reactions.
