2,4,6-Trichlorobenzaldehyde(CAT: L041137) is a chlorinated aromatic aldehyde featuring three chlorine atoms symmetrically substituted at the 2, 4, and 6 positions of the benzene ring and a formyl group at the para position. This compound is valued as an intermediate in the synthesis of agrochemicals, dyes, and pharmaceuticals. The electron-withdrawing chlorine atoms increase the reactivity of the aldehyde group, making it suitable for electrophilic aromatic substitution and condensation reactions. It is commonly used in the preparation of biologically active heterocycles and polymer additives. Its stability, reactivity, and halogen-rich structure also make it a useful reagent in environmental and materials chemistry research.
