α-Benzoin oxime is widely used in analytical chemistry as a selective reagent for the detection and determination of metal ions, particularly copper. It forms stable complexes with copper ions, which can be utilized in gravimetric and spectrophotometric methods to quantify copper in various samples, including ores, alloys, and environmental samples. Additionally, it serves as a chelating agent in separation processes, aiding in the extraction and purification of specific metals. In organic synthesis, α-benzoin oxime is employed as a ligand or intermediate in the preparation of complex organic compounds. Its ability to act as a stabilizer in certain chemical reactions also makes it valuable in industrial applications.
