Description

5-Pyrimidinemethanol, -α--Ethyl-2-Methyl-, (-α-S)- (9Ci) is a high-purity, chiral pyrimidine derivative of significant interest in advanced organic synthesis. This compound serves as a critical chiral building block and intermediate for the development of novel active pharmaceutical ingredients (APIs) and fine chemicals. It is primarily needed by research institutions and manufacturers in the pharmaceutical, agrochemical, and specialty chemical industries engaged in asymmetric synthesis and drug discovery programs. Our supply ensures consistent quality and reliable availability for your most demanding R&D and scale-up projects.

Application

• Pharmaceutical Intermediate: A key chiral synthon in the asymmetric synthesis of potential drug candidates, particularly for antiviral, anticancer, and central nervous system (CNS) agents.
• Agrochemical Research: Used in the development of novel, optically active pesticides and herbicides where specific stereochemistry is crucial for biological activity.
• Ligand and Catalyst Development: Serves as a precursor for creating chiral ligands and organocatalysts used in enantioselective transformations.
• Fine Chemical Synthesis: Employed in the multi-step synthesis of complex, high-value specialty chemicals and advanced materials.
• Academic and Industrial R&D: A valuable reagent for methodological studies in organic chemistry, particularly in exploring new C-C bond formation and functionalization of heterocycles.
