Description

Oxirane, 2-Ethynyl-3-Pentyl-, (2R,3R)-Rel- (9Ci) is a specialized chiral epoxide building block of significant interest in advanced organic synthesis. Its unique structure, featuring both an ethynyl and a pentyl substituent on an oxirane ring, makes it a valuable precursor for constructing complex, stereodefined molecular architectures. This high-purity intermediate is primarily sought by research and development teams in the pharmaceutical and fine chemical industries for applications in asymmetric synthesis and medicinal chemistry.

Application

• Pharmaceutical Intermediate: A key chiral synthon for the research and development of novel active pharmaceutical ingredients (APIs), particularly in constructing complex heterocycles and side chains.
• Asymmetric Synthesis: Utilized in stereoselective ring-opening reactions to introduce functionalized chiral centers into target molecules with high enantiomeric purity.
• Ligand and Catalyst Development: Serves as a precursor for synthesizing novel chiral ligands and organocatalysts used in enantioselective transformations.
• Fine Chemical Production: Employed in the multi-step synthesis of specialty chemicals, agrochemicals, and advanced materials requiring specific stereochemistry.
• Academic and Industrial R&D: Used in methodological studies and process development for new synthetic routes in organic chemistry.

Quality Control

Every batch of Oxirane, 2-Ethynyl-3-Pentyl-, (2R,3R)-Rel- (9Ci) is produced and analyzed under strict quality management protocols to ensure consistency and high purity for research and development applications. Our products undergo rigorous quality testing, including chiral purity analysis, to ensure compliance with industry standards. Certificates of Analysis (COA) detailing identity, purity, and enantiomeric excess are available upon request.

Storage

Preserve in a tightly closed container, protected from light. Store in a cool, dry, and well-ventilated area at controlled room temperature (typically 15-25°C). Keep away from heat, sparks, and open flame. Due to the reactive nature of epoxides, store separately from strong acids, bases, and oxidizing agents.
