L-Carnitine Hydrochloride (CAS 6645-46-1) is the hydrochloride salt of levocarnitine, a vitamin-like compound presenting as a white to off-white crystalline powder for pharmaceutical, nutraceutical, food fortification and animal nutrition applications, where the salt form offers improved handling and formulation stability compared with free-base carnitine. It presents as a white to off-white crystalline powder, freely soluble in water (log P −4.518), with a melting point of 65 °C.
The hydrochloride salt form delivers improved handling characteristics and formulation stability relative to free-base carnitine, making it a preferred carnitine source in pharmaceutical, nutritional, and feed manufacturing where consistent solubility and dosage performance are required.
