This compound serves as a key intermediate in the synthesis of kinase inhibitors, particularly for JAK and CDK families, due to its privileged pyrrolopyrimidine scaffold. Researchers utilize it to develop novel anticancer and anti-inflammatory agents via Suzuki-Miyaura or Buchwald-Hartwig couplings. It is also employed in fluorescent probe development for cellular imaging studies. The bromo and chloro substituents enable sequential functionalization for library diversification in combinatorial chemistry.
