Reference 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.
Trans-1,2-cyclohexanedisulfonic acid: An optically active linker for coordination polymers
Racemic 1,2-cyclohexanedisulfonic acid was prepared from cyclohexene oxide via the cyclic trithiocarbonate and isolated as its barium salt. Optical resolution was achieved by crystallization with (-)-(R,R)-1,2-cyclohexane diamine; the absolute configuration was established by X-ray crystallography of this salt, [C6H10(NH3)2][C6H10(SO3)2]. Solid-state structures were investigated of the racemic acidic sodium disulfonate Na(H5O2)[C6H10(SO3)2] and the optically active disulfonates Na2[C6H10(SO3)2]¡¤1.8H2O and Ag(NH2Me2)[C6H10(SO3)2]. Optically active trans-1,2-cyclohexanedisulfonic acid was prepared in four steps from cyclohexene oxide.
