TCI B6399, 1-([1,1'-Biphenyl]-2-yl)ethan-1-one (CAS 2142-66-7), also known as 2-acetylbiphenyl, is an aromatic methyl ketone built on an ortho-substituted biphenyl framework. The reactive α-position supports aldol and Claisen–Schmidt condensations, α-halogenation, and cyclocondensation routes to heterocycles. Its ortho geometry is particularly useful for intramolecular cyclisations leading to fluorenone and other fused polycyclic systems. Offered by AMI Scientific in 1 g and 5 g packs, it fits both exploratory chemistry and longer multi-step sequences; consult the lot Certificate of Analysis for applicable specifications.
