Used as an intermediate in the synthesis of pharmaceutical compounds, particularly in the development of kinase inhibitors for cancer treatment. It serves as a building block in medicinal chemistry due to its reactive chloromethyl group, which allows for easy attachment to other molecular structures. Commonly employed in the preparation of pyrimidine-based derivatives with biological activity, including antiviral and anti-inflammatory agents. Also utilized in agrochemical research for designing novel pesticides with improved efficacy.
