First search is 1-Chlorobutane, with molecular formula C4H9Cl. The following searches were tert-butyl chloride, 2-chlorobutane, 1-Chloro-2methylpropane, (2S)-2-Chlorobutane, and (2R)-2-Chlorobutane. The molecular formula of the remaining five searches also happen to be C4H9Cl, same as my unknown E55672. At this point it is grim to eliminate any of the possible compounds being they have identical molecular formulas. Further investigating into the other properties would have to be scrutinized in order to eliminate from these six possibilities. I will now compare the density values of these six compound to my actual
