l-carnitine vs d carnitine Typical chromatograms of after degradation under (a) L-Carnitine and acetyl-L-carnitine roles and

the object of this invention is to provide a preparation method of high-purity L-carnitine, which is characterized in that to prepare L-carnitine with a purity being above 97%, wherein the content of D-carnitine is below 2%, by detecting and controlling the content of chiral material and chiral intermediate during the whole synthetic process which is started from S-epichlorohydrin, wherein the method include the following steps: the present invention provide a optically pure compound of formula (II) wherein R represents methyl, ethyl, isopropyl, butyl or benzyl, and X represents Cl or Br

These tests are often used in roadside or workplace drug testing due to their quick results

Antioxidante: La L-carnitina tiene propiedades antioxidantes que pueden ayudar a proteger las clulas del dao causado por los radicales libres, contribuyendo as al envejecimiento saludable y la salud general
