SODIUM ARSENITE Chemical compatibility with O-rings, rubbers, & plastics

Sodium Arsenite is a white, crystalline inorganic compound with the chemical formula NaAsO2. It is used in various industrial and chemical applications, primarily as a pesticide and herbicide. Sodium Arsenite is employed in agriculture to control weeds, insects, and other pests, providing effective protection for crops. It is also used as a wood preservative, preventing decay and extending the life of wood products. In the chemical industry, Sodium Arsenite is used as a reagent in the synthesis of various organic compounds and as a source of arsenic in certain chemical reactions. Proper handling and storage of Sodium Arsenite are essential to prevent accidents and ensure safety, as it is highly toxic and can pose significant health risks if ingested or inhaled. Proper safety measures, including the use of appropriate protective equipment and adherence to handling protocols, are essential when working with Sodium Arsenite. Its effectiveness as a pesticide and preservative makes it a valuable chemical in various applications, although its use requires careful control to prevent hazards.
