The patent mentioned the optical activity of L-3-chloro-2-hydroxypropyl trimethylamine, but it did not provide the content of the optical isomers in the chiral materials nor how to detect it accurately.JP3287567A The article "Synthesis of L-(-)-carnitine" (Chinese Journal of Synthetic Chemistry, vol 12, 2004) described in detail that to prepare the L-3-chloro-2-hydroxypropyl trimethylamine by amination from the chiral epichlorohydrin, then to produce the L-(-)-chloride-3-cyan-2-hydroxypropyl trimethylamine by cyanidation, and finally to obtain L-carnitine by hydrolysis, during which the specific rotation of the epichlorohydrin, the intermediate and the product was detected
