Used as an intermediate in the synthesis of sulfonylurea herbicides, particularly in the production of certain rice herbicides. It plays a key role in building the pyrimidine ring structure that provides selectivity and efficacy against broadleaf and grassy weeds in paddy fields. Its sulfinyl group allows for further chemical modifications, enabling the development of more potent and environmentally stable agrochemicals. Commonly utilized in proprietary herbicide formulations where precise weed control is required with minimal impact on the crop.
