ARSENIC(III) OXIDE A.C.S. PRIMARY STANDARD (99.95-100.05%) (C005B-015125)

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.
