This disubstituted pyrimidine compound is a vital heterocyclic intermediate for pharmaceutical and agrochemical synthesis. Reactive chlorine atom enables nucleophilic substitution and coupling reactions to construct diversified molecular skeletons. It is widely applied to develop antibacterial, anti-inflammatory and antitumor drugs, improving medicinal activity and molecular stability. It also acts as raw material for high-efficiency fungicides and herbicides in crop protection. Moreover, it can be used to synthesize biochemical reagents and fine chemical derivatives. Its excellent reaction performance supports extensive use in new drug research, pesticide production and organic synthetic innovation.

This chemical has moderate toxicity and irritating properties. Inhalation of fine powder may cause respiratory discomfort, perform operations under ventilation with dust-proof mask. Direct skin contact leads to redness and itching, wear protective gloves and clean contaminated skin timely. Eye contact results in intense stinging and mucosal injury, flush eyes with running water for more than fifteen minutes. Thermal decomposition produces toxic chloride gas. Keep far from open flame, high temperature and oxidizing substances. Do not store with food. Dispose waste following hazardous waste norms to prevent personal harm and environmental pollution.
