CAS NO.	77-73-6
Formula & Weight	C₁₀H₁₂ (MW: 132.20)
Chemical Structure
Technical Specifications	Purity (GC): ≥ 99.0% (High Purity Grade Appearance: Colorless to pale yellow clear liquid/solid (Melts @ ~33°C) Color (Pt-Co): ≤ 30 (Water White) Water Content: ≤ 0.03% Trimer & Co-dimers: ≤ 1.0% Boiling Point: ~170°C
Key Applications	DCPD is essential for advanced materials and synthesis: Reaction Injection Molding (RIM): Used to produce large, impact-resistant parts for trucks, buses, and construction equipment. Requires ≥99% purity for optimal polymerization speed and properties. Optical Resins (COC/COP): Monomer for Cyclic Olefin Copolymers, used in high-end optical lenses and medical packaging. EPDM Rubber: The third monomer (diene) in Ethylene-Propylene-Diene rubber, providing cross-linking sites for vulcanization. Unsaturated Polyester Resins (UPR): Improves air-drying properties and heat resistance in high-grade marine and sanitary resins. Fine Chemical Synthesis: Precursor for Adamantane (antiviral drugs) and Glutaraldehyde.
Packaging & Storage	Packaging: 200kg Steel Drum / ISO Tank. Storage: Store below 30°C to prevent dimerization and peroxide formation. Contains antioxidant (BHT) for stability.

Royalchem offers ≥99.0% Dicyclopentadiene with low color and moisture.
