Used as a key intermediate in the synthesis of phosphodiesterase inhibitors, particularly in the development of drugs targeting respiratory diseases such as chronic obstructive pulmonary disease (COPD) and asthma. Its structure enables selective interaction with enzyme active sites, enhancing therapeutic efficacy. Also employed in research for novel anti-inflammatory agents due to its ability to modulate cellular signaling pathways. Solubility and stability properties make it suitable for formulation in oral and inhaled dosage forms.
