Used as an intermediate in the synthesis of kinase inhibitors, particularly in the development of anticancer agents. Its structure allows for selective functionalization, making it valuable in medicinal chemistry for constructing complex heterocyclic systems. Commonly employed in research settings to develop compounds targeting protein kinases involved in cell signaling pathways. Also utilized in solid-phase synthesis due to the trityl group’s protective properties, enabling controlled reactions and improved yield in multi-step organic syntheses.
