Description

3-Cyclopentene-1-Carbonyl Chloride, 1,2,2-Trimethyl- (9Ci) is a specialized organic intermediate featuring a reactive acid chloride group on a functionalized cyclopentene ring. This compound matters for its role as a key building block in the synthesis of complex molecules, enabling the introduction of the 1,2,2-trimethylcyclopentene carbonyl moiety. It is primarily needed by research and development chemists and process scale-up teams in the pharmaceutical and agrochemical industries for creating novel active ingredients and fine chemicals.

Application

• Pharmaceutical Intermediate: Serves as a crucial precursor in the synthesis of novel drug candidates, particularly those requiring a sterically defined, functionalized cyclopentane/cyclopentene core structure.
• Agrochemical Synthesis: Used in the research and development of advanced pesticides and herbicides, where its unique carbon skeleton can contribute to specific biological activity.
• Material Science Research: Acts as a monomer or cross-linking agent in the development of specialized polymers with tailored thermal or mechanical properties.
• Organic Synthesis Building Block: Employed in academic and industrial R&D for constructing complex natural product analogs and other sophisticated organic molecules via amide or ester formation.
• Ligand and Catalyst Development: Utilized to create novel chiral ligands or organocatalysts for asymmetric synthesis applications.
• Flavor and Fragrance Industry: Potential intermediate for the synthesis of specialty aroma chemicals with woody or amber notes derived from its terpene-like structure.

Quality Control

Our 3-Cyclopentene-1-Carbonyl Chloride, 1,2,2-Trimethyl- (9Ci) is produced under strict quality management protocols. Each batch undergoes rigorous analytical testing to ensure identity, purity, and consistency. Certificates of Analysis (COA) detailing specific results for purity, assay, and impurity profiles are available upon request to support your quality assurance and regulatory documentation needs.

Storage

Preserve in a tightly closed container, protected from light. Store in a cool, dry, well-ventilated place at controlled room temperature (typically 15-25°C). Due to its hygroscopic (moisture-sensitive) nature, containers must be kept tightly sealed under an inert atmosphere (e.g., nitrogen or argon) after opening to prevent decomposition. Keep away from heat, sparks, open flames, and incompatible materials such as strong bases, alcohols, and amines.
