Used as a key intermediate in the synthesis of pharmaceutical compounds, particularly in the development of kinase inhibitors for cancer treatment. Its structure allows for easy modification and binding to biological targets, making it valuable in medicinal chemistry. Commonly found in research settings for designing drugs that modulate enzyme activity, especially in signaling pathways involved in tumor growth. Also utilized in the creation of novel compounds for neurological and inflammatory disorders due to its ability to cross cell membranes and interact with central nervous system receptors.
