1-Bromo-3-chlorobenzene is widely used as an intermediate in organic synthesis, particularly in the production of pharmaceuticals and agrochemicals. Its dual halogen substitution makes it a versatile building block for constructing more complex molecules. In the pharmaceutical industry, it is employed in the synthesis of active pharmaceutical ingredients (APIs) and fine chemicals. Additionally, it serves as a key reagent in cross-coupling reactions, such as Suzuki and Heck reactions, which are essential for creating carbon-carbon bonds in drug development. In agrochemicals, it is utilized to produce herbicides, pesticides, and fungicides, contributing to crop protection and agricultural productivity. Its stability and reactivity also make it valuable in material science for developing specialty polymers and dyes.
