Useful:

• Physical properties: Yellow or orange monoclinic crystal or powder; a red allotrope modification also known; density 3.46 g/cm3; melts at 310°C; boils at 707°C; insoluble in water; soluble in liquid ammonia and alkalies.
• Uses: Arsenic(III) sulfide is used in the treatment of acute promyelocytic leukemia. It is an inorganic photoresist used in the fabrication of photonic crystals and 3-D nanostructures. It is also used as an acousto-optic material, pigment, tanning agent and chalcogenide glass for infrared optics. Further, it is used as an analytical test for presence of dissimilatory arsenic-reducing bacteria (DARB). manufacture of glass, particularly infrared-transmitting glass; manufacture of oil cloth, linoleum; in electrical semiconductors, photoconductors; as pigment; for depilating hides; in pyrotechnics.
