2,6-Dichlorobenzaldehyde(CAT: R048294) is an aromatic aldehyde with the molecular formula C₇H₄Cl₂O. Characterized by two chlorine atoms at the 2 and 6 positions of the benzene ring and a reactive formyl group, it appears as a white to pale yellow crystalline solid. This compound is a key intermediate in the synthesis of pharmaceuticals, agrochemicals, dyes, and specialty chemicals. The electron-withdrawing chlorine atoms enhance the electrophilic nature of the aldehyde group, making it highly reactive in condensation and substitution reactions. 2,6-Dichlorobenzaldehyde is also utilized in the preparation of functionalized heterocycles and Schiff bases for advanced material and medicinal research.
