Specification
L(-)-Carnitine hydrochloride (CAS NO.6645-46-1) is also named as (-)-(3-Carboxy-2-hydroxypropyl)trimethylammonium chloride ; (R)-3-Carboxy-2-hydroxy-N,N,N-trimethyl-1-propanaminium chloride ; (R)-Carnitine hydrochloride ; L-Carnitine chloride ; L-Carnitine hydrochloride ; LC-80 ; Levocarnitine chloride ; UNII-J3Y5E6IKS3 ; l-(3-Carboxy-2-hydroxypropyl)trimethylammonium chloride ; l-Carnitine chloride ; l-Carnitine hydrochloride . L(-)-Carnitine hydrochloride (CAS NO.6645-46-1) is white to slightly beige crystalline powder. It is toxic. It will produce toxic nitrogen oxides and hydrogen chloride fumes by heat. So the storage environment should be ventilate, low-temperature and dry.
