Description

2,3-Epoxy-5-Vinylnorbornane is a specialized, high-value epoxidized norbornene derivative. This compound serves as a critical, reactive intermediate for advanced polymer synthesis and fine chemical manufacturing. It is primarily sought by R&D chemists and process engineers in the pharmaceutical, agrochemical, and performance materials sectors for constructing complex molecular architectures.

Application

• Pharmaceutical Intermediate: Used in the synthesis of active pharmaceutical ingredients (APIs) and complex drug candidates, leveraging its strained epoxide and vinyl groups for selective ring-opening and cross-coupling reactions.
• Advanced Polymer Monomer: A key building block for synthesizing specialty polymers, including cycloolefin copolymers (COCs) and resins with high thermal stability, transparency, and low dielectric constant.
• Agrochemical Synthesis: Employed in creating novel herbicides, fungicides, and plant growth regulators where the norbornane skeleton provides structural rigidity and bioactivity.
• Epoxy Resin Modifier: Acts as a reactive diluent and toughness enhancer in high-performance epoxy resin formulations for composites, adhesives, and coatings.
• Cross-linking Agent: Utilized in radiation-curable coatings and inks, where its dual functionality allows for efficient network formation.
• Fine Chemical Research: Serves as a versatile scaffold in academic and industrial R&D for exploring new catalytic transformations and material properties.

Quality Control

Our 2,3-Epoxy-5-Vinylnorbornane is manufactured under strict quality management systems. Each batch undergoes rigorous analytical testing, including GC, HPLC, and NMR, to ensure high purity and consistent performance. Certificates of Analysis (COA) detailing identity, assay, and impurity profiles are provided with every shipment to support your quality assurance and regulatory needs.

Storage

Preserve in a tightly closed container, protected from light. Store in a cool, dry, well-ventilated place at a controlled room temperature (15-25°C). Due to its hygroscopic (moisture-sensitive) nature, the container must be kept tightly sealed under an inert atmosphere (e.g., nitrogen or argon) after opening to prevent degradation.
