This pyrimidine heterocyclic intermediate owns active chlorine and methyl groups for substitution and coupling reactions. It is mainly used to synthesize antibacterial, anti-inflammatory and anti-tumor drugs, boosting molecular bioactivity and stability. It also serves as key raw material for high-efficiency fungicides and herbicides in agrochemical production. Additionally, it can be applied to prepare biochemical reagents and fine chemical derivatives. Its stable structure and good reactivity make it widely adopted in new drug research, pesticide development and organic synthesis fields.

The compound has moderate toxicity and irritating effects. Inhalation of dust may cause respiratory discomfort, work with ventilation and dust mask. Skin contact will trigger redness and itching, wear protective gloves and clean skin in time. Eye exposure leads to severe stinging damage, rinse eyes with running water for over fifteen minutes. Thermal decomposition generates toxic chloride gas. Keep away from fire, high temperature and oxidants. Store separately from food. Dispose waste as hazardous chemicals to avoid personal injury and environmental pollution.
