Description

2(1H)-Pyrimidinethione, 5-Methoxy- (9Ci) is a specialized heterocyclic sulfur compound that serves as a valuable building block in advanced organic synthesis. Its unique pyrimidinethione core functionalized with a methoxy group makes it a critical intermediate for developing novel active pharmaceutical ingredients (APIs) and functional materials. This high-purity chemical is essential for research and development chemists in the pharmaceutical, agrochemical, and material science industries seeking to create new molecules with targeted properties.

Application

• Pharmaceutical Intermediate: A key synthon for the research and development of novel drug candidates, particularly in antiviral, anticancer, and central nervous system (CNS) therapeutic areas.
• Agrochemical Synthesis: Used in the creation of advanced pesticides, herbicides, and fungicides where the pyrimidine scaffold is a common active moiety.
• Material Science Research: Serves as a precursor for designing organic semiconductors, ligands for metal-organic frameworks (MOFs), and other functional organic materials.
• Chemical Biology & Proteomics: Employed as a reactive handle or probe in studying enzyme inhibition and protein interactions due to its thione functionality.
• Academic & Industrial R&D: A fundamental reagent for methodological development in organic chemistry, including heterocyclic chemistry and cross-coupling reactions.
