POTASSIUM PERMANGANATE Chemical compatibility with O-rings, rubbers, & plastics

Potassium permanganate (KMnO4) is a strong oxidizing agent widely used in various applications, including water treatment, disinfection, and as a chemical reagent. It appears as a dark purple or bronze-colored crystalline solid. In water treatment, it is used to remove iron, manganese, and hydrogen sulfide by oxidation. In medical settings, it serves as an antiseptic for treating dermatitis and fungal infections. Additionally, it is employed in organic chemistry for oxidation reactions. Potassium permanganate's effectiveness and versatility make it valuable in both industrial and laboratory settings. However, it must be handled with care due to its strong oxidizing properties, which can cause burns and ignite flammable materials upon contact.
