General description

Arsenic (III) oxide, also referred to as arsenic trioxide, is an amphoteric oxide that is used as a raw material to produce several arsenic-based compounds.

Application

Arsenic (III) oxide is used
  • In the synthesis of arsenic pentafluoride (AsF5) by static fluorination method in a closed system.
  • In the preparation of arsenic-doped ZnO films by adding As2O3 to zinc acetate, 2-methoxyethanol, and monoethanolamine by sol-gel spin coating method.

Alpha-fetoprotein (AFP)-producing gastric cancer (AFPGC), represented by the production of AFP, has a more aggressive behavior than common gastric cancer. The underlying mechanisms are not well understood. Arsenic trioxide (As(2)O(3)) is used clinically to treat acute promyelocytic leukemia(APL) and has
