Application


  • Antioxidant and therapeutic potential: Pyrogallol demonstrates significant anti-inflammatory, sedative, antidiabetic, and antioxidant capabilities across both in vitro and in vivo models, as evidenced by a comprehensive phenolic profiling of Atractylis aristata Batt (Abid et al., 2024).

  • Photo-switchable collector applications: The utility of pyrogallol-derived compounds as photo-switchable collectors in the flotation process for lithium aluminate recycling has been explored, highlighting its role in enhancing raw material recovery (Zgheib et al., 2024).

  • Biomedical applications in hydrogels: Pyrogallol is integrated into the design of a hydrogel, focusing on biomedical applications such as wound healing and drug delivery, offering insights into the versatile uses of pyrogallol in medical materials (Weian et al., 2024).
