Description

Oxiranemethanol, 3-(1-Pentynyl)-, (2S-Trans)- (9Ci) is a specialized chiral epoxide building block of significant interest in advanced organic synthesis. Its unique structure, featuring both an epoxide ring and an alkyne moiety, makes it a versatile precursor for constructing complex, stereodefined molecular architectures. This high-value intermediate is primarily sought after by research and development teams in the pharmaceutical and agrochemical sectors for the synthesis of novel active ingredients and fine chemicals. Its defined stereochemistry is critical for applications requiring precise three-dimensional control.

Application

• Pharmaceutical Intermediate: A key chiral synthon for the research and development of novel active pharmaceutical ingredients (APIs), particularly in oncology and antiviral drug discovery.
• Agrochemical Synthesis: Used in the creation of advanced, stereospecific pesticides and herbicides where biological activity is highly dependent on molecular configuration.
• Ligand and Catalyst Development: Serves as a precursor for synthesizing chiral ligands and organocatalysts used in asymmetric synthesis.
• Material Science Research: Employed in the development of novel polymers and functional materials with tailored properties derived from its reactive functional groups.
• Academic & Industrial R&D: A valuable tool for synthetic organic chemists in universities and corporate labs exploring new reaction methodologies and complex molecule construction.
