Description

Cyclooctanecarbonyl Chloride (7Ci,9Ci) is a specialized organic acid chloride derivative of cyclooctane, serving as a high-value building block in advanced organic synthesis. Its primary value lies in its ability to introduce the cyclooctylcarbonyl moiety, a key structural feature for modifying molecular properties. This reagent is essential for research and development chemists in the pharmaceutical, agrochemical, and material science industries, where it is used to create novel compounds with tailored functionalities. The product is supplied under strict quality control to ensure batch-to-batch consistency for critical synthetic applications.

Application

• Pharmaceutical Intermediate: Key building block for the synthesis of active pharmaceutical ingredients (APIs) and novel drug candidates, particularly those requiring a lipophilic cyclooctane backbone.
• Agrochemical Synthesis: Used in the research and production of advanced pesticides, herbicides, and fungicides where the cyclooctyl group can enhance bioavailability and environmental stability.
• Polymer & Material Science: Acts as a monomer or modifying agent in the production of specialty polymers, coatings, and advanced materials with unique thermal or mechanical properties.
• Ligand & Catalyst Development: Employed in the synthesis of complex organic ligands and catalysts for asymmetric synthesis and transition metal catalysis.
• Fine Chemical & Flavor/Fragrance Precursor: Serves as a starting material for the synthesis of complex fine chemicals and aroma molecules.
• Academic & Industrial R&D: A valuable reagent for method development and exploratory chemistry in both academic laboratories and corporate R&D centers.

Quality Control

Our Cyclooctanecarbonyl Chloride is manufactured under strict process controls to ensure high purity and reliability for sensitive synthetic applications. Each batch undergoes comprehensive analytical testing, including chromatography (GC/HPLC) and spectroscopic methods (NMR, IR), to verify identity, purity, and the absence of critical impurities. A detailed Certificate of Analysis (COA) is provided with every shipment, documenting all relevant specifications. We adhere to a cGMP-aligned quality management system to support our customers in regulated research and development.

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 and highly volatile nature, the container must be kept tightly sealed under an inert atmosphere (e.g., nitrogen or argon) after initial opening to prevent moisture absorption and decomposition. Keep away from heat, sparks, open flames, and strong bases. Store separately from incompatible materials.
