Description

Cyclopropanecarbonyl Chloride, 2-Methyl-2-(1-Methylethenyl)-, cis- (9Ci) is a specialized organic intermediate featuring a reactive acid chloride functional group attached to a substituted cyclopropane ring. This compound matters for its role as a key building block in the synthesis of complex molecules, enabling the introduction of the cyclopropane moiety, a structure valued for its unique conformational and biological properties. It is primarily needed by research chemists and process development teams in the pharmaceutical and agrochemical industries for creating novel active ingredients and fine chemicals.

Application

• Pharmaceutical Intermediate: Serves as a critical precursor in the synthesis of proprietary drug candidates, particularly those targeting central nervous system (CNS) disorders or infectious diseases.
• Agrochemical Synthesis: Used in the development of advanced pesticides and herbicides, where the cyclopropane ring can enhance biological activity and environmental stability.
• Material Science Research: Acts as a monomer or cross-linking agent in the development of novel polymers with specific thermal or mechanical properties.
• Chemical Biology Probes: Employed in the creation of molecular probes and labeled compounds for studying enzyme mechanisms and biological pathways.
• Catalyst Ligand Development: Utilized for constructing sophisticated ligand frameworks in asymmetric catalysis and organometallic chemistry.
• Flavor & Fragrance Ingredient Synthesis: A potential intermediate for manufacturing complex aroma chemicals that require the cyclopropane structural motif.

Quality Control

Our Cyclopropanecarbonyl Chloride, 2-Methyl-2-(1-Methylethenyl)-, cis- (9Ci) is produced under strict quality management protocols. Each batch undergoes rigorous analytical testing, including chromatographic purity analysis and identity confirmation, to ensure it meets the high standards required for research and process chemistry. Certificates of Analysis (COA) detailing specific batch results 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 area at controlled room temperature (15-25°C). Due to its hygroscopic (moisture-sensitive) nature and reactivity as a strong acid/organic solvent, the container must be kept tightly sealed under an inert atmosphere (e.g., nitrogen or argon) to prevent degradation. Keep away from heat, open flames, and incompatible materials such as bases, alcohols, and amines.
