Application

Pyrazolone T serves as a key intermediate in the synthesis of azo dyes and pigments due to its dual-reactive sites for diazo coupling. In analytical chemistry, it functions as a chelating agent for transition metal detection (e.g., iron, copper) via spectrophotometric methods. The compound’s sulfonic acid group enhances water solubility, making it valuable for developing hydrophilic pharmaceutical derivatives or biochemical probes.
