Used in the synthesis of pharmaceuticals, particularly as an intermediate in developing antifungal and antiviral agents. It serves as a building block in heterocyclic chemistry, enabling the construction of complex imidazole-based structures. Commonly employed in medicinal chemistry for modifying bioactive molecules to enhance potency and selectivity. Also utilized in agrochemical research for developing new crop protection agents. Its aldehyde group allows for easy functionalization, making it valuable in combinatorial chemistry and drug discovery.
