N-Benzoyl-N-phenylhydroxylamine (BPHA) is widely used as a chelating agent in analytical chemistry for the extraction and determination of metal ions. It is particularly effective in separating and quantifying trace amounts of metals such as vanadium, molybdenum, and uranium from complex matrices. BPHA forms stable complexes with these metals, enabling their selective isolation and measurement in environmental, industrial, and biological samples. Additionally, it is employed in spectrophotometric methods for metal analysis due to its ability to produce distinct color changes upon complexation, facilitating accurate detection. In industrial applications, BPHA is utilized in metal purification processes to remove impurities and enhance the quality of final products. Its role in research and quality control laboratories is also significant, contributing to advancements in metallurgical and environmental studies.
