Quality Control of (1S,3R)-1,2,2-Trimethylcyclopentane-1,3-dicarboxylic acid. The reaction of aromatic heterocyclic molecules with protons is called protonation. Aromatic heterocycles are more basic than benzene due to the participation of heteroatoms. Compound: (1S,3R)-1,2,2-Trimethylcyclopentane-1,3-dicarboxylic acid, is researched, Molecular C10H16O4, CAS is 560-09-8, about Resolution of the racemates of DL-carnitine. Author is Mueller, Detlef M.; Strack, Erich.
A rational and cheap method is reported for the direct resolution of DL-carnitine. D-(+)-Camphoric acid, L-(-)-camphoric acid, dibenzoyl-D-(-)-tartaric acid, or L-(+)-tartaric acid were used to sep. DL-carnitine into its optically active components. Resolution was achieved by repeated fractional crystallization in alc. solution with the appropriate acid, or by combined fractionation with a suitable pair of acids. The resulting salts can be decomposed quant. with water, dilute acids, ether/water, or ion exchanger, to give pure, optically active carnitines. The optically active acids may also be recovered pure and used again for racemate separation
