This pyrimidine derivative is a pivotal heterocyclic intermediate widely utilized in pharmaceutical and agrochemical synthesis. Chlorine and methylthio groups provide active reaction sites for nucleophilic substitution and coupling reactions, facilitating the construction of diverse pyrimidine molecular skeletons. It serves as core raw material to synthesize anti-inflammatory, antibacterial and anti-tumor drugs, enhancing molecular biological activity and medicinal stability. In pesticide industry, it is applied to manufacture high-performance fungicides and herbicides for crop protection. It also acts as precursor for biochemical reagents and fine chemical additives. Its superior reaction activity and stable structure render it indispensable in new drug development, pesticide innovation and organic synthetic research.

The compound carries moderate toxicity and irritant properties. Inhalation of fine powder may induce respiratory discomfort and throat irritation, all operations should be performed in ventilated surroundings with dust-proof mask. Direct skin contact easily causes redness, itching and mild inflammation, wear protective gloves and clean contaminated skin timely. Eye exposure leads to severe stinging and mucosal damage, continuously rinse eyes with running water for more than fifteen minutes. Accidental ingestion will impair digestive organs. Thermal decomposition releases toxic chloride and sulfur-containing gas. Keep away from open fire, high temperature and strong oxidants. Separate storage from food supplies. Waste substances need standard hazardous waste disposal to avoid personal injury and environmental pollution.
