Povidone Iodine (CAS 25655-41-8) is a stable iodophor complex of polyvinylpyrrolidone and triiodide ions, supplied as a yellowish to reddish-brown powder that releases free iodine gradually for broad-spectrum microbicidal action in hospital disinfection, preoperative skin preparation, veterinary wound care, and water purification. It releases free iodine gradually, ensuring prolonged efficacy without significant staining in diluted forms.
