3. 👕 Textiles

Main use: Used in the treatment of dyed textiles to improve color fastness to light, prevent yellowing of wool products, and prevent fading of synthetic fiber fabrics.

4. 🔬 Scientific Research

Main use: As a research reagent, it is used in photodegradation research, materials science (such as studying how to introduce UV absorption functions into polymers or coatings), and environmental science research (as a model compound to study the environmental fate of sulfonic acid substances in aquatic systems).
