Overview
Vinylcyclopentane is an organic compound with a five-membered cyclopentane ring and a reactive vinyl (-CH=CH2) group. It belongs to the class of cyclic alkenes and is primarily used in industrial chemistry as a building block for more complex molecules. As a volatile liquid, it requires careful handling due to its flammability. Its molecular structure makes it useful in polymerization reactions and as a precursor in synthesizing specialty chemicals.
Physical and Chemical Properties
Vinylcyclopentane is a colorless liquid with a characteristic hydrocarbon odor. Its density is lower than water (0.81 g/cm³), and it boils at approximately 100–102°C. The compound is insoluble in water but miscible with common organic solvents like ethanol or acetone. The vinyl group contributes to its reactivity, particularly in addition and polymerization reactions. It is sensitive to heat and open flames, requiring storage under inert conditions to prevent degradation or hazardous reactions.
Main Applications
In industrial settings, vinylcyclopentane serves as an intermediate for synthesizing pharmaceuticals, fragrances, and polymer modifiers. Its reactive double bond enables copolymerization with monomers like styrene or ethylene to alter material properties. It is also employed in research laboratories for studying ring-opening reactions and catalytic processes. Some niche applications include its use in adhesives and coatings, where it enhances flexibility or cross-linking density.
Safety and Storage
Due to its flammability (Flash Point ~-7°C), vinylcyclopentane must be stored in tightly sealed containers away from heat sources. Static electricity discharge can ignite vapors, necessitating grounded equipment during transfer. Personal protective equipment (PPE) such as nitrile gloves and vapor respirators is recommended. Spills should be contained with inert absorbents, and fire extinguishers (CO2 or dry chemical) must be accessible. Always consult SDS before handling.
B2B Procurement Guide
Industrial buyers should prioritize suppliers with ISO certification and batch-specific analysis reports. Common packaging includes 200L steel drums or 20L cans, with prices varying by purity (typically 95–99%) and order volume. Key procurement considerations include testing for peroxides (if stored long-term), verifying nitrogen blanket protection during shipping, and evaluating lead times. Some manufacturers offer custom synthesis for higher-purity grades.
