Building fluorescent sensors by template polymerization: the preparation of a fluorescent sensor for D-fructose was written by Wang, Wei;Gao, Shouhai;Wang, Binghe. And the article was included in Organic Letters in 1999.Product Details of 166821-88-1 This article mentions the following:

The application of mol. imprinting in making fluorescent sensors was hampered by the lack of suitable fluorescent tags, which would respond to the binding event with significant fluorescence intensity changes. The authors have designed and synthesized a fluorescent monomer which allows for the preparation of fluorescent sensors of cis diols using mol. imprinting methods. This monomer was used for the preparation of sensitive fluorescent sensors for D-fructose. In the experiment, the researchers used many compounds, for example, 2-(2-(Bromomethyl)phenyl)-5,5-dimethyl-1,3,2-dioxaborinane (cas: 166821-88-1Product Details of 166821-88-1).

2-(2-(Bromomethyl)phenyl)-5,5-dimethyl-1,3,2-dioxaborinane (cas: 166821-88-1) belongs to organobromine compounds. Bromine is more electronegative than carbon (2.9 vs 2.5). Consequently, the carbon in a carbon–bromine bond is electrophilic, i.e. alkyl bromides are alkylating agents. Commercially available organobromine pharmaceuticals include the vasodilator nicergoline, the sedative brotizolam, the anticancer agent pipobroman, and the antiseptic merbromin.
