Description

Exo-2-Norbornylzinc Bromide is a highly reactive organozinc reagent, specifically an exo-norbornyl Grignard-type compound. This chemical is valued for its role as a versatile building block in advanced organic synthesis, particularly for introducing the sterically demanding and rigid norbornyl moiety. It is primarily sought after by research chemists and process development scientists in the pharmaceutical, agrochemical, and advanced materials sectors for constructing complex molecular architectures.

Application

• Pharmaceutical Intermediate: Key reagent for the synthesis of novel active pharmaceutical ingredients (APIs), especially those requiring the unique three-dimensional structure of the norbornyl group to modulate biological activity.
• Agrochemical Synthesis: Used in creating advanced herbicides, fungicides, and insecticides where the norbornyl unit can enhance stability and efficacy.
• Cross-Coupling Reactions: Serves as a nucleophilic partner in Negishi, Kumada, and other transition-metal catalyzed cross-coupling reactions to form carbon-carbon bonds.
• Polymer & Material Science: Employed in the development of specialty polymers, ligands for catalysis, and organic electronic materials.
• Asymmetric Synthesis: Useful in stereoselective synthesis due to the defined stereochemistry of the exo-norbornyl group.
• Organic Methodology Research: A valuable tool for academic and industrial research into new organometallic reaction pathways.

Quality Control

Our Exo-2-Norbornylzinc Bromide is produced under stringent quality control protocols to ensure batch-to-batch consistency and high reactivity. Typical quality assessments include titration for active zinc content and analytical techniques to confirm structure and purity. A comprehensive Certificate of Analysis (COA) detailing purity, assay, and solvent content is provided with each shipment to support your quality assurance and R&D documentation.

Storage

Preserve in a tightly closed container, protected from light. Store under an inert atmosphere (argon or nitrogen) at recommended temperatures between 2°C and 8°C. This compound is moisture-sensitive (hygroscopic) and easily oxidized; all handling and packaging must be performed under anhydrous, oxygen-free conditions to maintain stability and efficacy.
