Alpha Lipoic Acid (ALA), as per IP and USP specifications, is a fine crystalline powder renowned for its potent antioxidant properties. It plays a crucial role as a co-factor in enzymatic reactions, supporting cellular energy production and protecting against oxidative stress. ALA's purity is ensured with an assay of 99.0% to 101.0% on a dried basis, complemented by stringent limits on moisture content (not exceeding 0.5%) and residue on ignition (not more than 0.1%). It exhibits excellent solubility in alcohol, chloroform, and ether, with slight solubility in water. These qualities make ALA indispensable in pharmaceutical and dietary supplement formulations aimed at bolstering antioxidant defenses and promoting overall health.
