Used primarily as a reagent in organic synthesis, this compound is valuable for introducing the 2,4-dichlorophenyl group into various molecules through diazonium coupling reactions. It is particularly useful in the preparation of dyes, pigments, and other aromatic compounds, where the diazonium group acts as a key intermediate. Additionally, it finds application in the synthesis of pharmaceuticals and agrochemicals, where the 2,4-dichlorophenyl moiety is often a critical structural component. Its reactivity under mild conditions makes it a preferred choice for constructing complex organic frameworks efficiently.
