Abstract
A reversed-phase high performance liquid chromatographic method for analysis of L-carnitine is described. The improved method is able to provide a high resolution between L-carnitine and crotonoylbetaine, a major impurity and degradation product, and suitable for quantitative analysis of L-carnitine in pharmaceutical formulations, such as solution, tablets, and capsules. The resolution, linearity, accuracy and reproducibility of the method are discussed.
