#arsenic hydride
- Arsines — A class of hydrated chemical compounds of arsenic, representing structural analogues of amines and phosphines, obtained by replacing hydrogen atoms in arsenic hydride (gaseous arsine) with organic hydrocarbon radicals. These compounds are highly toxic, flammable, and volatile, being intensively studied in organometallic chemistry and historically used as chemical warfare agents or as precursors in advanced semiconductor material doping.
