Used as an intermediate in the synthesis of pharmaceutical compounds, particularly in the development of kinase inhibitors for cancer treatment and phosphodiesterase (PDE) inhibitors for central nervous system (CNS) disorders such as depression and sleep aids. It serves as a versatile building block in medicinal chemistry due to its ability to interact with biological targets through hydrogen bonding and hydrophobic interactions. Its structure is often modified to enhance potency, selectivity, and reduce side effects in drug candidates. Also employed in research settings for structure-activity relationship (SAR) studies, as well as in the development of anti-inflammatory agents.
