Description

1,3-Cyclopentadiene is a fundamental organic building block and a highly reactive diene, essential for the Diels-Alder cycloaddition reaction. Its unique conjugated double-bond system makes it a critical intermediate in the synthesis of complex organic frameworks, including pharmaceuticals, agrochemicals, and advanced materials. This compound is vital for R&D chemists and production facilities in the fine chemical, pharmaceutical, and polymer industries seeking to create novel cyclic structures.

Application

• Diels-Alder Reactions: Serves as the quintessential diene component for synthesizing norbornene derivatives and other complex bicyclic compounds.
• Pharmaceutical Intermediates: Key starting material for the production of active pharmaceutical ingredients (APIs) and other bioactive molecules.
• Agrochemical Synthesis: Used in the manufacture of pesticides, herbicides, and other crop protection agents.
• Polymer & Resin Production: Acts as a monomer or co-monomer in the synthesis of specialty polymers, resins, and elastomers.
• Fine Chemical Manufacturing: Employed in the synthesis of fragrances, flavors, and other high-value specialty chemicals.
• Metallocene Catalyst Synthesis: A crucial precursor for producing cyclopentadienyl ligands used in metallocene catalysts for olefin polymerization.
• Academic & Industrial R&D: Fundamental reagent for research in synthetic organic chemistry and materials science.

Quality Control

Our 1,3-Cyclopentadiene is produced and handled under stringent quality management systems. Each batch undergoes comprehensive analytical testing, including Gas Chromatography (GC), to ensure high purity and consistency. A detailed Certificate of Analysis (COA) is provided with every shipment, confirming compliance with agreed specifications. We support cGMP and ISO standards for industrial and research applications.

Storage

Preserve in a tightly closed container, protected from light. Due to its highly volatile nature, store in a cool, well-ventilated place, preferably under an inert atmosphere (e.g., nitrogen) to prevent dimerization and oxidation. Recommended storage temperature is 2-8°C (refrigerated) for extended stability. Keep away from heat, sparks, open flames, and oxidizing agents.
