1-Hydroxymethylbenzocyclobutene（Cat No.:M066714）is an organic compound featuring a benzocyclobutene core—a four-membered cyclobutene ring fused to a benzene ring—with a hydroxymethyl group (-CH₂OH) attached at the 1-position. This structure imparts both ring strain and aromatic stability, making it useful in organic synthesis and materials science. The hydroxymethyl functionality allows for further chemical modifications, such as etherification or esterification. It serves as a valuable intermediate in the preparation of polymers, photoresists, and advanced electronic materials, particularly in microelectronics due to its thermally induced ring-opening ability that enhances crosslinking and dielectric properties.
