Pharmaceutical Intermediate Key pyrimidine heterocyclic building block for anticancer, antiviral, anti-inflammatory and kinase inhibitor drugs. It can undergo selective substitution, Suzuki coupling and amination reactions to construct complex pyrimidine drug skeletons.

Agrochemical Intermediate Used for synthesis of high-efficiency fungicides, herbicides and insecticides; pyrimidine skeleton with halogen substitution improves biological activity and target binding selectivity.

Organic Synthesis Building Block Widely used in cross-coupling and nucleophilic substitution reactions to prepare multi-substituted pyrimidine derivatives and nitrogen heterocyclic fine chemicals.

Optoelectronic & Functional Material Intermediate Applied in the synthesis of pyrimidine-containing fluorescent probes, organic semiconductor materials and OLED intermediates.
