Used in pharmaceutical research as a potent and selective inhibitor of specific kinase enzymes involved in inflammatory and immune-mediated diseases. Shows promise in preclinical studies for treating autoimmune conditions such as rheumatoid arthritis and psoriasis by modulating signaling pathways that drive chronic inflammation. Its structure enables high target specificity, reducing off-target effects. Often employed in formulation development for oral dosage forms due to favorable solubility and stability profiles when paired with hydrochloride salt. Also utilized as a reference standard in analytical testing during drug development.
