Description

(S)-2-Vinyl-Oxirane is a chiral epoxide monomer of significant interest in advanced organic synthesis. Its value lies in its highly reactive oxirane ring and vinyl group, which enable its use as a versatile building block for creating optically active polymers and fine chemicals. This product is essential for researchers and manufacturers in the pharmaceutical, agrochemical, and specialty polymer industries seeking to introduce chirality and specific functional groups into their molecular architectures.

Application

• Chiral Intermediate in Pharmaceutical Synthesis: Serves as a key precursor for active pharmaceutical ingredients (APIs) requiring specific stereochemistry.
• Agrochemical Product Development: Used in the synthesis of enantiomerically pure herbicides, fungicides, and plant growth regulators.
• Specialty Polymer & Resin Production: Acts as a monomer for creating chiral polymers with potential applications in advanced materials, liquid crystals, and coatings.
• Ligand & Catalyst Preparation: Employed in the synthesis of chiral ligands and organocatalysts for asymmetric synthesis.
• Fine Chemical & Flavor/Fragrance Synthesis: Utilized as a building block for complex, optically active molecules in the flavor and fragrance industry.
• Cross-linking Agent: The epoxide functionality allows it to act as a cross-linker in polymer networks, modifying material properties.

Quality Control

Our (S)-2-Vinyl-Oxirane is produced under strict quality management protocols. Each batch undergoes comprehensive analytical testing, including chiral purity analysis by GC or HPLC, to ensure high enantiomeric excess (ee) and chemical purity. A Certificate of Analysis (COA) detailing specific results for assay, optical rotation, and impurity profiles is provided with every shipment to guarantee consistency and traceability for your critical applications.

Storage

Preserve in a tightly closed container, protected from light. Store in a cool, well-ventilated area away from heat sources and incompatible materials. Due to its highly volatile nature, containers should be kept tightly sealed and under an inert atmosphere (e.g., nitrogen) if opened, to prevent polymerization or degradation. Recommended long-term storage temperature is 2-8°C.
