Product overview
Benzocyclobutene comprises a benzene ring fused to a four-membered carbocycle, combining an aromatic system with a strained small ring.
Application areas
Depending on the synthesis route and project requirements, this product may also be suitable for other related organic synthesis applications.
Potential uses
- Benzocyclobutene (BCB) contains a strained four-membered ring fused to benzene. On heating, the BCB unit can ring-open to a reactive o-xylylene intermediate, which enables cycloaddition and thermally cured polymers; BCB-functional monomers are investigated for high-performance coatings and dielectric materials.
