15-Bromopentadecanoic acid (cas: 56523-59-2) belongs to organobromine compounds. Many of the organo bromine compounds are relatively nonpolar. Bromine is more electronegative than carbon (2.8 vs 2.5) and hence the carbon in a carbon–bromine bond is electrophilic in nature. The principal reactions for organobromides include dehydrobromination, Grignard reactions, reductive coupling, and nucleophilic substitution.Product Details of 56523-59-2

The Effect of Surface Polarity on the Electrochemical Double Layer and Its Influence on the Measurement of the Standard Rate Constant of Electron Transfer was written by Eggers, Paul K.;Hibbert, D. Brynn;Paddon-Row, Michael N.;Gooding, J. Justin. And the article was included in Journal of Physical Chemistry C in 2009.Product Details of 56523-59-2 This article mentions the following:

The influence of surface polarity and, hence, the elec. double layer on long-range electron transfer was studied using 35 different electrode constructs. These constructs were prepared using 5 different lengths of ferrocene-modified alkanethiols (of general formula HS(CH2)nCONHCH2Fc where n was 7, 10, 11, 14, and 15 and Fc refers to ferrocene) mixed with an appropriate ratio of hydroxyl-terminated to Me-terminated alkanethiols as diluents. The mixtures of diluents in different ratios served not only to sep. and dilute the redox-active species but also to control the surface polarity of the self-assembled monolayer (SAM). The ratios of the 3 components in each SAM were 1:20:0, 1:16.6:3.4, 1:13.4:6.6, 1:10:10, 1:6.6:13.4, 1:16.6:3.4, and 1:0:20 of the ferrocene-, hydroxyl-, and Me-terminated species, resp. The formal redox potential and electron transfer rate constant were measured for each construct. It was found, 1st, that formal potentials changed according to the theory of interfacial potential distribution and, 2nd, that rate constants measured using cyclic voltammetry are strongly influenced by the Stern layer of the elec. double layer, which forms at the SAM-solution interface. In the experiment, the researchers used many compounds, for example, 15-Bromopentadecanoic acid (cas: 56523-59-2Product Details of 56523-59-2).
