Used primarily in HPLC labeling, this chemical acts as a derivatization agent to enhance the detection of analytes. It reacts with specific functional groups in target molecules, forming derivatives that are more easily detected by UV or fluorescence detectors. This improves the sensitivity and selectivity of HPLC analysis, making it valuable in pharmaceutical research, environmental testing, and biochemical studies where precise quantification of compounds is critical. Its nitrobenzyl group aids in creating stable, detectable derivatives, ensuring accurate and reliable results in complex sample matrices.
