Description

(R)-(+)-1,2-Epoxyoctane CAS NO 77495-66-0 is a high-purity, chiral epoxide building block essential for asymmetric synthesis. Its value lies in its ability to introduce the (R)-configured oxirane moiety into target molecules with high stereochemical fidelity, enabling the production of enantiomerically pure intermediates. This compound is critically needed by researchers and process chemists in the pharmaceutical, agrochemical, and advanced materials industries for developing novel active ingredients and functional polymers.

Application

• Pharmaceutical Intermediate: Key chiral synthon for the synthesis of enantiomerically pure drugs, particularly in constructing β-blockers, antifungal agents, and other bioactive molecules.
• Agrochemical Synthesis: Used in the production of chiral pesticides and herbicides where specific stereochemistry is required for optimal activity and environmental profile.
• Polymer & Material Science: Serves as a monomer or cross-linking agent for creating specialty polymers with tailored properties, such as epoxy resins or chiral stationary phases for chromatography.
• Asymmetric Catalysis Research: A valuable substrate for developing and testing new chiral catalysts and methodologies in academic and industrial R&D settings.
• Fine Chemical Production: Employed in the multi-step synthesis of complex flavors, fragrances, and other high-value specialty chemicals.

Quality Control

Our (R)-(+)-1,2-Epoxyoctane is manufactured under strict quality management systems. Each batch undergoes rigorous analytical testing, including chiral purity assessment by GC or HPLC, to ensure it meets the high standards required for synthetic applications. A comprehensive Certificate of Analysis (COA) detailing identity, purity, enantiomeric excess, and impurity profile is provided with every shipment to guarantee traceability and consistency.

Storage

Preserve in a tightly closed container, protected from light. Store in a cool, dry, and well-ventilated area at room temperature (15-25°C). Keep away from heat, sparks, open flames, and strong oxidizing agents. Due to its light-sensitive nature, containers should be amber glass or otherwise opaque.
