Description

(S)-(-)-1,2-Epoxy-5-Hexene, Gc 99% is a high-purity, chiral epoxide building block of significant importance in asymmetric synthesis. Its enantiomeric purity and reactive oxirane ring make it a valuable precursor for the production of optically active pharmaceuticals, agrochemicals, and fine chemicals. This compound is essential for researchers and process chemists in the pharmaceutical, agrochemical, and specialty chemical industries seeking to introduce stereochemistry into complex molecular architectures.

Application

• Chiral Intermediate in Pharmaceutical Synthesis: A key starting material for the synthesis of enantiomerically pure active pharmaceutical ingredients (APIs), particularly those requiring specific stereocenters.
• Agrochemical Precursor: Used in the development of chiral herbicides, fungicides, and insecticides where biological activity is stereospecific.
• Fine Chemical and Fragrance Building Block: Employed in the synthesis of complex, high-value flavor and fragrance compounds.
• Ligand and Catalyst Development: Serves as a precursor for chiral ligands and auxiliaries used in asymmetric catalysis.
• Polymer Modification: Can be used to introduce reactive epoxy and alkene functionalities into polymer chains for cross-linking or further functionalization.
• Academic and R&D Laboratories: A critical reagent for methodological development in organic synthesis and stereochemistry studies.

Quality Control

Our (S)-(-)-1,2-Epoxy-5-Hexene is produced under stringent quality management protocols to ensure batch-to-batch consistency and high enantiomeric purity. Each lot is analyzed using advanced chromatographic techniques (GC, HPLC) to verify identity, assay, and enantiomeric excess (ee). A comprehensive Certificate of Analysis (COA) detailing purity, physical properties, and chiral purity is provided with every shipment, supporting compliance in cGMP and research applications.

Storage

Preserve in a tightly closed container, protected from light. Store in a cool, well-ventilated place at 2-8°C (refrigerated) or as specified on the label. Due to its highly volatile nature, ensure containers are securely sealed and stored upright. Keep away from heat, sparks, open flames, and strong oxidizing agents.
