Description

Bicyclo[2.2.1]Hept-5-En-2-Ol, 2-Ethynyl-, Endo- (9Ci) is a specialized, high-purity organic intermediate featuring a unique norbornene scaffold with both hydroxyl and ethynyl functional groups. This compound matters for its role as a critical building block in advanced organic synthesis, enabling the creation of complex molecular architectures. It is primarily needed by R&D chemists and process development scientists in the pharmaceutical, agrochemical, and advanced materials sectors for applications in polymer chemistry, click chemistry, and the synthesis of novel active ingredients.

Application

• Pharmaceutical Intermediate: Serves as a key precursor in the synthesis of novel drug candidates, particularly those requiring rigid, three-dimensional frameworks.
• Polymer & Material Science: Used as a functional monomer or cross-linking agent in the development of specialty polymers, resins, and advanced materials with tailored properties.
• Click Chemistry Reagent: The ethynyl group makes it an ideal substrate for copper-catalyzed azide-alkyne cycloaddition (CuAAC) reactions, a cornerstone of bioconjugation and material surface modification.
• Agrochemical Synthesis: Employed in the research and development of new pesticides and herbicides, where its structural complexity can contribute to unique modes of action.
• Ligand & Catalyst Development: Acts as a starting material for synthesizing novel chiral ligands or organometallic catalysts used in asymmetric synthesis.
• Academic & Industrial R&D: A valuable tool for exploratory chemistry in universities and corporate research laboratories focused on organic methodology development.

Quality Control

Our Bicyclo[2.2.1]Hept-5-En-2-Ol, 2-Ethynyl-, Endo- (9Ci) is manufactured under strict quality management protocols to ensure batch-to-batch consistency and high purity. Each lot undergoes comprehensive analytical characterization, including HPLC, GC, NMR, and IR spectroscopy, to verify identity and purity. A detailed Certificate of Analysis (COA) documenting all test results is 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, and well-ventilated place at a controlled room temperature (typically 15-25°C). This product is hygroscopic (moisture-sensitive); therefore, containers must be kept tightly sealed and consideration should be given to storage under an inert atmosphere for long-term preservation of quality.
