Description

Bicyclo[2.2.1]Hept-5-Ene-2-Methanol, 3-Ethenyl-, (1R,2S,3R,4S)-Rel- (9Ci) is a high-purity, stereochemically defined bicyclic compound serving as a critical chiral building block and advanced pharmaceutical intermediate. Its rigid, functionalized norbornene structure makes it invaluable for synthesizing complex molecules with precise three-dimensional architecture. This compound is essential for researchers and manufacturers in pharmaceutical development, asymmetric catalysis, and advanced material science who require reliable access to high-quality, specialty intermediates.

Application

• Pharmaceutical Intermediate: Key chiral synthon for the synthesis of active pharmaceutical ingredients (APIs), particularly in neurology and antiviral drug candidates.
• Asymmetric Catalysis: Used as a ligand precursor or a core scaffold for developing novel chiral catalysts and auxiliaries.
• Advanced Polymer Chemistry: Serves as a monomer or cross-linking agent for creating specialty polymers with unique thermal and mechanical properties via ring-opening metathesis polymerization (ROMP).
• Agrochemical Research: Intermediate in the development of new generation, stereospecific pesticides and herbicides.
• Material Science: Building block for liquid crystals, optical materials, and other functional organic materials requiring a rigid, bicyclic framework.
• Academic & R&D: A valuable tool for synthetic organic chemists exploring new methodologies and complex natural product synthesis.
