Product Description:
TBPE is primarily used as a reagent in analytical chemistry for the spectrophotometric determination of various substances. It acts as a chromogenic agent, forming colored complexes with specific analytes, which can be measured to quantify their concentration. This makes it valuable in environmental testing, particularly for detecting heavy metals like cadmium and zinc in water samples. Additionally, TBPE is employed in biochemical research to study enzyme activity and interactions, as its color change properties provide a visual indicator of chemical reactions. Its stability and sensitivity make it a reliable tool in both laboratory and industrial settings for precise analytical measurements.
