Description

3(2H)-Pyridazinone, 4,5-Dihydro-5-Methyl-6-Phenyl-, (5R)- is a high-purity chiral intermediate of significant importance in advanced organic synthesis. Its value lies in its defined stereochemistry, which is critical for producing enantiomerically pure active pharmaceutical ingredients (APIs) and fine chemicals. This compound is essential for research and development chemists and manufacturers in the pharmaceutical and agrochemical industries seeking to build complex molecular architectures with high stereoselectivity.

Application

• Pharmaceutical Intermediate: A key chiral building block for the synthesis of novel therapeutic agents, particularly in central nervous system (CNS) and cardiovascular drug discovery.
• Agrochemical Synthesis: Used in the research and development of advanced pesticides and herbicides where specific stereochemistry influences biological activity.
• Asymmetric Catalysis Research: Serves as a precursor or ligand in the development of new chiral catalysts for stereoselective reactions.
• Fine Chemical Production: Employed in the manufacture of specialty chemicals requiring high enantiomeric purity for flavors, fragrances, or advanced materials.
• Academic & Industrial R&D: A valuable compound for methodological studies in organic chemistry, particularly in heterocyclic and stereochemistry research.
