一般描述
氧化砷（III），也称为三氧化二砷，是一种可用作合成多种砷基化合物原料的两性氧化物。
应用
氧化砷（III）可用于：
- 在封闭体系中通过静态氟化法合成五氟化砷（AsF5）。
- 在醋酸锌、2-甲氧基乙醇和单乙醇胺中加入As2O3，通过溶胶-凝胶自旋涂覆法制备砷掺杂 ZnO 薄膜。

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
