Used primarily in analytical chemistry for the detection and quantification of carbonyl compounds, particularly aldehydes and ketones. It forms stable derivatives with these compounds, which can then be analyzed using techniques like HPLC or UV-Vis spectroscopy. This makes it valuable in environmental monitoring, food safety, and industrial quality control processes where precise measurement of carbonyl content is essential. Additionally, it aids in research studies focused on understanding oxidative stress and degradation pathways in various materials.
