41. The commercial preparations of this drug are the racemic mixture of both enantiomers of the compound. 42. The new process begins by enantiopure trifluoromethylated phenyl ethanol being joined to a racemic morpholine precursor. 43. Racemic synephrine has been resolved using ammonium 3-bromo-camphor-8-sulfonate.44. If the value is near 0.5, the crystal may be racemic or twinned. 45. Syntheses of racemic galanthamine have been reported by Wang in 2006 and by Saito in 2008. 46. It has SERT = 18795 nM . The racemic compound was resolved into its constituent enantiomers. 47. However, the majority of studies have been conducted with a racemic mixture of the two enantiomers. 48. "' Racemethorphan "'refers to the racemic mixture of both of these stereoisomers. 49. Kent and co-workers have since tested racemic crystallography on a wide range of protein molecules. 50. But racemic mixtures are not characteristic of life, which depends on left-handed amino acids alone.
