Used as a key intermediate in the synthesis of agrochemicals, particularly herbicides and insecticides. Its structure allows for the development of compounds with selective activity against weeds and pests in crop protection. It is also utilized in the preparation of pharmaceuticals where pyrimidine derivatives exhibit biological activity, including antimicrobial and anti-inflammatory properties. The chlorine and ethoxy groups enable further chemical modifications, making it valuable in research and development of new active ingredients in both agricultural and medicinal chemistry.
