Description

Dicyclopentadiene CAS NO 77-73-6 is a versatile and reactive hydrocarbon dimer derived from cyclopentadiene, serving as a critical building block in high-performance chemical synthesis. Its unique bridged, bicyclic structure makes it an essential raw material for producing resins, polymers, and specialty chemicals with enhanced thermal stability and mechanical properties. This compound is particularly valuable for manufacturers in the petrochemical, polymer, and agrochemical industries seeking to develop advanced materials and intermediates.

Application

• Unsaturated Polyester Resins (UPR): A key monomer for producing high-performance resins used in automotive parts, marine hulls, and construction materials.
• Hydrocarbon Resins (C5 Resins): Acts as a primary component in the manufacture of tackifiers for adhesives, sealants, and rubber compounding.
• Ethylene-Propylene-Diene Monomer (EPDM) Rubber: Serves as the diene component (ENB - Ethylidene Norbornene) in the synthesis of EPDM, providing superior crosslinking sites for vulcanization.
• Flame Retardants: Used as an intermediate in the synthesis of reactive and additive flame retardants for plastics and textiles.
• Agrochemicals and Pharmaceuticals: A valuable precursor for synthesizing complex molecules like pesticides, insecticides, and pharmaceutical intermediates (e.g., camphor analogs).
• Specialty Chemicals and Fragrances: Employed in Diels-Alder reactions to create high-value chemicals, including fragrances and fine chemical intermediates.
• Fuel Additives: Investigated for use in improving the octane rating and combustion properties of fuels.

Quality Control

Our Dicyclopentadiene is manufactured under stringent process controls to ensure batch-to-batch consistency and high purity. Quality is verified through a comprehensive suite of analytical tests including gas chromatography (GC) for assay and impurity profiling. We provide full traceability and Certificates of Analysis (COA) are available for every shipment, confirming compliance with agreed specifications.

Storage

Preserve in a tightly closed container, protected from light. Store in a cool, well-ventilated area away from heat, sparks, and open flame. Recommended storage temperature is between 15-25°C (59-77°F). This product is easily oxidized and should be stored under an inert atmosphere (e.g., nitrogen) when in partially filled containers to prevent degradation and polymerization. Keep away from strong oxidizing agents.
