Used as an intermediate in the synthesis of quinazoline-based bioactive compounds, particularly in the development of kinase inhibitors for cancer treatment, such as those targeting EGFR (Epidermal Growth Factor Receptor). Its structure enables further reactions to create derivatives that inhibit receptors involved in cancer cell growth, supporting binding to enzyme active sites and the creation of targeted therapies. Also employed in research settings to design new quinazoline-based molecules with potential antitumor and anti-inflammatory properties. Additionally, utilized in organic chemistry to construct macrocycles or ligands for catalysts, where the chloropropoxy group serves as a reactive linker enhancing solubility and biological target binding.
