Used as an intermediate in organic synthesis, particularly in pharmaceutical and agrochemical industries. It serves as a building block for creating complex molecules due to the presence of both chlorine and triflate groups, which are reactive sites for cross-coupling reactions like Suzuki or Heck reactions. Commonly employed in the development of active pharmaceutical ingredients (APIs) where aryl triflates are needed to form carbon-carbon bonds. Also utilized in the synthesis of specialty polymers and functional materials requiring specific electronic or thermal stability properties.
