Used as a key intermediate in the synthesis of pharmaceutical compounds, particularly in the development of kinase inhibitors for cancer treatment. It serves as a building block in medicinal chemistry due to its structural similarity to purine bases, enabling interactions with biological targets such as enzymes and receptors. Its carboxylic acid functionality allows for easy derivatization, facilitating the formation of amides, esters, and other functional groups important in drug design. Also employed in research settings to develop new bioactive molecules with potential anti-inflammatory, antiviral, or neuroprotective activities.
