Application


  • Triphosgene in Organic Synthesis: Triphosgene is highlighted for its efficacy in organic reactions over the last decade, offering a safer and more convenient alternative to phosgene due to its solid state and lower volatility. so it can be used in various synthetic applications, enhancing reaction conditions and safety in laboratories(Ganiu et al., 2020).

  • Biodegradable Hydrogel Synthesis: Bis(trichloromethyl) carbonate was utilized in the one-step synthesis of biodegradable curcumin-derived hydrogels aimed at soft tissue filler applications post-breast cancer surgery. This represents a significant advancement in biomaterials, focusing on improving post-surgical recovery and compatibility (Shpaisman et al., 2012).
