Description

5-Norbornene-2-Exo-Carbonyl Chloride, 2-Chloro-Exo-3-Methyl- (6Ci) is a highly reactive and versatile bicyclic organic intermediate, specifically functionalized with an acid chloride group. Its value lies in its unique strained-ring structure, which enables its use as a key building block for synthesizing complex molecules with tailored properties. This compound is essential for researchers and manufacturers in the pharmaceutical, agrochemical, and advanced materials sectors, particularly for developing novel polymers, catalysts, and active pharmaceutical ingredients (APIs).

Application

• Pharmaceutical Intermediate: Serves as a critical precursor in the synthesis of novel drug candidates, especially those requiring a rigid, functionalized norbornene scaffold.
• Polymer Chemistry: Acts as a monomer or co-monomer for the production of specialty polymers via ring-opening metathesis polymerization (ROMP) or other addition polymerization techniques.
• Agrochemical Synthesis: Used in the development of advanced pesticides and herbicides where the norbornene core imparts specific biological activity and stability.
• Ligand and Catalyst Development: Functionalized to create novel chiral ligands and organometallic catalysts for asymmetric synthesis.
• Advanced Material Research: Incorporated into materials for electronics, coatings, and composites to modify thermal, mechanical, or optical properties.
• Cross-linking Agent: Utilized to introduce reactive sites into polymer backbones for creating cross-linked networks with enhanced durability.

Quality Control

Our production of 5-Norbornene-2-Exo-Carbonyl Chloride adheres to stringent quality protocols to ensure batch-to-batch consistency and high purity for sensitive synthetic applications. All materials are characterized using advanced analytical techniques including NMR, HPLC, and GC. A comprehensive Certificate of Analysis (COA) detailing purity, identity, and impurity profiles is provided with each shipment to support your quality assurance and regulatory needs.

Storage

Preserve in a tightly closed container, protected from light. Store in a cool, dry, and well-ventilated area at temperatures between 2°C and 8°C (refrigerated) to maximize stability. Due to its hygroscopic and moisture-sensitive nature, containers must be kept sealed under an inert atmosphere (e.g., nitrogen or argon) when not in use. Keep away from strong acids, bases, and oxidizing agents.
