Used as an intermediate in the synthesis of sulfonylurea herbicides, particularly in the production of certain rice herbicides. It plays a key role in constructing the pyrimidine ring system found in active agrochemical compounds. Its chloro and thioether functional groups allow for sequential substitution reactions, enabling the introduction of sulfonylurea moieties. This makes it valuable in developing herbicides with high selectivity and potency against broadleaf and grassy weeds in paddy fields.
