Description

Cyclopropanecarbonyl Chloride, 3-Ethenyl-2,2-Dimethyl-, trans- (9Ci) is a specialized, high-purity 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 unique cyclopropane moiety into target structures. It is primarily needed by R&D chemists and process development scientists in the pharmaceutical and agrochemical industries for creating novel active ingredients and advanced materials.

Application

• Pharmaceutical Intermediate: A critical precursor in the synthesis of novel drug candidates, particularly those targeting central nervous system (CNS) disorders and infectious diseases.
• Agrochemical Synthesis: Used in the research and development of next-generation pesticides and herbicides, where the cyclopropane structure can confer specific biological activity.
• Material Science Research: Serves as a monomer or cross-linking agent in the development of specialty polymers with tailored thermal or mechanical properties.
• Chemical Biology & Proteomics: Employed as a reactive handle for bioconjugation, labeling proteins, or modifying biomolecules for study.
• Catalyst & Ligand Development: Acts as a starting material for synthesizing chiral ligands and organometallic catalysts used in asymmetric synthesis.
• Flavor & Fragrance Industry: Potential intermediate for creating synthetic aroma chemicals with unique, complex scent profiles.

Quality Control

Our Cyclopropanecarbonyl Chloride, 3-Ethenyl-2,2-Dimethyl-, trans- (9Ci) is manufactured under strict quality management systems. Every batch undergoes rigorous analytical testing to ensure high purity and consistent performance. We provide comprehensive Certificates of Analysis (COA) with each shipment, detailing key parameters such as assay, isomeric purity, and impurity profiles. Our quality commitment supports applications requiring cGMP compliance for pharmaceutical development.

Storage

Preserve in a tightly closed container, protected from light. Store in a cool, dry, and well-ventilated place at a 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.
