Sodium arsenite is primarily used as a certified primary standard reducing titrant in bromatometric and iodometric volumetric titrations. It is essential in analytical chemistry for the accurate determination of halogens and other oxidizing agents. Additionally, it finds applications in the preparation of arsenic-containing compounds in various chemical syntheses. Due to its toxicity, it is also used in controlled environments for research purposes, particularly in studies related to arsenic's effects and behavior in biological systems.
