Used in pharmaceutical research as a key intermediate in the synthesis of kinase inhibitors, particularly targeting tyrosine kinases involved in cancer cell proliferation. Shows potential in developing treatments for solid tumors due to its ability to cross cell membranes and bind selectively to ATP pockets in target proteins. Also explored for anti-inflammatory applications owing to its structural similarity to known PDE4 inhibitors. Commonly employed in structure-activity relationship (SAR) studies to optimize potency and reduce off-target effects in drug candidates.
