Description

Cyclopentylacetylene 90 is a high-purity, highly volatile organic building block featuring a terminal alkyne group attached to a cyclopentyl ring. This unique structure makes it a valuable intermediate for synthesizing complex molecules in advanced research and industrial applications. It is primarily sought after by pharmaceutical, agrochemical, and specialty chemical manufacturers for constructing novel compounds and active ingredients.

Application

• Pharmaceutical Intermediate: A key synthon in the synthesis of active pharmaceutical ingredients (APIs), particularly for creating novel ring systems and carbon scaffolds.
• Agrochemical Synthesis: Used in the development of new pesticides, herbicides, and fungicides, leveraging its reactivity for structural diversification.
• Material Science Research: Serves as a monomer or precursor in the development of specialty polymers and advanced organic materials.
• Cross-Coupling Reactions: An essential reagent in Sonogashira, Glaser, and other palladium-catalyzed coupling reactions to form carbon-carbon bonds.
• Ligand and Catalyst Development: Employed in the preparation of specialized ligands for catalysis and metal-organic frameworks (MOFs).
• Fine Chemical Production: Acts as a versatile building block for synthesizing flavors, fragrances, and other high-value specialty chemicals.

Quality Control

Our Cyclopentylacetylene 90 is manufactured under strict quality control protocols to ensure batch-to-batch consistency and high purity. Each lot is analyzed to confirm identity, potency, and impurity profiles. A comprehensive Certificate of Analysis (COA) detailing specifications such as assay (by GC), identity (by IR/NMR), and purity is provided with every shipment to support your quality assurance and regulatory needs.

Storage

Preserve in a tightly closed container, protected from light. Due to its highly volatile nature, store in a cool, well-ventilated place, ideally at 2-8°C (refrigerated) or as specified on the label. Keep away from heat, sparks, open flames, and oxidizing agents. Containers should be kept tightly sealed when not in use to prevent evaporation and potential moisture ingress.
