Used as a key intermediate in the synthesis of agrochemicals, particularly herbicides and plant growth regulators. Its structure allows for easy modification to form active ingredients that target specific enzymes in weeds, improving crop selectivity. Also employed in the development of pharmaceutical candidates due to the bioactive nature of pyrimidine derivatives, especially in medicinal chemistry research focused on kinase inhibitors. The hydroxyl and chloro groups provide reactive sites for further chemical transformations, making it valuable in building complex molecules.
