This is a vital substituted pyrimidine intermediate with active chlorine and methyl groups, which can undergo nucleophilic substitution, coupling and cyclization reactions to construct various heterocyclic compounds. It is mainly utilized for the synthesis of anti-tumor, antibacterial and anti-inflammatory pharmaceuticals, effectively improving the biological activity and metabolic stability of drug molecules. In agrochemical industry, it acts as a core raw material for manufacturing fungicides, herbicides and insecticides for crop protection. Moreover, it can be used to prepare biochemical reagents and fine chemical derivatives. It is widely applied in new drug research, pesticide development and advanced organic synthesis fields.

This chemical is a moderately irritating solid with slight toxicity. Inhalation of fine dust will irritate the respiratory tract and cause cough or throat discomfort. All operations shall be performed in a well-ventilated area with dust-proof masks and protective gloves. Direct skin contact may lead to redness and itching; eye contact will cause stinging and mucosal injury. In case of exposure, rinse the affected area with plenty of running water for more than 15 minutes immediately. Thermal decomposition will generate toxic chloride fumes. Keep it far away from open flame, high temperature and strong oxidants. Do not store together with food and daily necessities. All waste shall be disposed of in accordance with hazardous waste regulations to prevent personal injury and environmental pollution.
