Application of 21436-03-3, Chemistry can be defined as the study of matter and the changes it undergoes. You’ll sometimes hear it called the central science because it is the connection between physics and all the other sciences, starting with biology.21436-03-3, Name is (1S,2S)-Cyclohexane-1,2-diamine, molecular formula is C6H14N2. In a patent, introducing its new discovery.
A 1,1?-bi-2-naphthol (BINOL)-based aldehyde containing four perfluoroalkyl groups has been designed and synthesized. It shows enantioselective fluorescence enhancement at 420 nm when treated with the enantiomers of trans-1,2-diaminocyclohexane in an organic/fluorous biphasic system. The enantiomeric excess of the diamine in methanol can be linearly correlated with the emission intensity of of the aldehyde in perfluorohexane (FC-72). This is the first example to determine the enantiomeric composition of a chiral molecule by using a fluorescent sensor in a fluorous/organic biphasic system. The mechanism of the reaction was investigated by NMR spectroscopy and mass spectrometry.
