Used as a protected pyrazole derivative in organic synthesis, particularly in pharmaceutical and agrochemical research. The SEM protecting group (trimethylsilylethoxymethyl) stabilizes the pyrazole nitrogen during multi-step reactions, allowing selective functionalization at other sites. The iodine atom serves as a handle for cross-coupling reactions such as Suzuki or Sonogashira couplings, enabling the construction of complex heterocyclic systems. Commonly employed in the development of bioactive molecules where pyrazole scaffolds are key structural elements.
