Description

Cyclopropylacetylene CAS NO 6746-94-7 is a highly versatile and reactive alkyne building block featuring a strained cyclopropyl ring. This unique molecular architecture makes it a critical intermediate for synthesizing complex molecules in advanced research and development. It is essential for pharmaceutical chemists and agrochemical researchers seeking to introduce cyclopropane motifs, which are known to enhance metabolic stability and biological activity.

Application

• Pharmaceutical Intermediate: Key building block for the synthesis of active pharmaceutical ingredients (APIs), particularly those containing cyclopropane rings for drug discovery.
• Agrochemical Synthesis: Used in the production of novel herbicides, fungicides, and insecticides where the cyclopropyl group imparts specific biological properties.
• Material Science Research: Serves as a monomer or precursor for developing specialized polymers and advanced organic materials with tailored properties.
• Organic Synthesis & Catalysis: A valuable reagent in cross-coupling reactions, cycloadditions, and other catalytic processes to construct complex carbon frameworks.
• Ligand & Catalyst Development: Employed in the preparation of novel ligands for metal-organic frameworks (MOFs) and asymmetric catalysis.
• Fine Chemical Production: Intermediate for manufacturing flavors, fragrances, and other high-value specialty chemicals.

Quality Control

Our Cyclopropylacetylene is produced under stringent quality management systems. Each batch undergoes comprehensive analytical testing, including GC, GC-MS, and NMR, to ensure high purity and consistent performance. Certificates of Analysis (COA) detailing identity, purity, and impurity profiles are provided with every shipment to support your quality assurance and regulatory compliance needs.

Storage

Preserve in a tightly closed container, protected from light. Store in a cool, well-ventilated place, away from heat, sparks, and open flames. Due to its highly volatile nature, containers must be kept tightly sealed and under an inert atmosphere (e.g., nitrogen or argon) when not in use to prevent evaporation and potential degradation. Recommended storage temperature is 2-8°C for long-term stability.
