2-Bromofluorene acts as a nonintrusive end-capping reagent in order to control molecular weights as well as in the generation of well-defined oligomers. It is used to prepare 2-bromo-9-cyclohepta-2,4,6-trienyl-9H-fluorene and 9,9-dihexylflorene. In addition to this, it is used in the preparation of poly(di-n-hexylfluorene)s end capped with 2-bromofluorene, 2-bromo-9,9-di-n-hexylfluorene and 9-bromoanthracene through Ni(0) mediated polymerization.

2-Bromofluorene is an organic compound that belongs to the group of aryl halides. It is used in the synthesis of polymers, pesticides and pharmaceuticals. 2-Bromofluorene has been shown to be mutagenic and carcinogenic in kidney cells. The chemical structure of 2-bromofluorene consists of two phenyl groups (benzene rings) connected by a single bromine atom. The optimal reaction condition for this chemical is hydrochloric acid in acetic acid with heat and high values of optical rotation. A number of compounds are derived from 2-bromofluorene, such as 4-chlorobenzophenone, 3-chlorobenzophenone, 4-bromoacetophenone, 3-bromoacetophenone, 2-(2'-hydroxyethoxy)ethanol, 2-(2'-hydroxyethyl)phenol, and 2-(2'-
