Cas no 6623-59-2 (1,2-dichloro-4-ethylbenzene)
1,2-Dichloro-4-ethylbenzene is a chlorinated aromatic compound with the molecular formula C?H?Cl?. It features a benzene ring substituted with two chlorine atoms at the 1- and 2-positions and an ethyl group at the 4-position. This structure imparts stability and reactivity suitable for use as an intermediate in organic synthesis, particularly in the production of agrochemicals, pharmaceuticals, and specialty chemicals. Its dichloro substitution pattern enhances electrophilic aromatic substitution selectivity, while the ethyl group contributes to solubility in organic solvents. The compound is typically handled under controlled conditions due to its potential toxicity and environmental persistence. Its consistent purity and well-defined reactivity make it a reliable building block for complex chemical transformations.
