L-Carnitine基地

L-Carnitine Base USP32/EP6 Charactristic:L-Carnitine forms white crystals or a white crystalline hygroscopic powder. It has a slight characteristic odor. L-Carnitine is extremely hygroscopic and even deliquescent and it can liquefy on exposure to air. L-Carnitine melts above 200under decomposition. L-Carnitine is highly soluble in water, in alcohol, in alkaline solutions, and in dilute mineral acids. It is practically insoluble in acetone or ethyl acetate.
