· NaAsO3

Sodium arsenite (NaAsO₃) is an inorganic compound classified as a semiconductor material with arsenic-based chemistry. While historically used in pesticides, herbicides, and wood preservation applications, it is primarily of interest in materials research for semiconductor and optoelectronic device development due to arsenic's electronic properties. Engineers encounter this compound primarily in specialized research contexts rather than mainstream industrial applications, where its toxicity requires careful handling and regulatory compliance.
