Thiosulfate

‌1. Gold Leaching‌

• A non-toxic alternative to cyanide for extracting gold from ores, leveraging its redox properties

‌2. Photography‌

• Acts as a fixing agent to remove unexposed silver halides from films and prints (e.g., sodium thiosulfate)

‌3. Medical & Pharmaceutical‌

• ‌Cyanide Poisoning Antidote‌: Sodium thiosulfate neutralizes cyanide by converting it to thiocyanate
  

• ‌Topical Treatments‌: Used in dermatology for antifungal and anti-inflammatory effects
  

‌4. Water Treatment‌

• Dechlorinates water by reducing residual chlorine and removes heavy metals (e.g., in industrial wastewater)
  

‌5. Agriculture‌

• Fertilizer component (e.g., ammonium thiosulfate) providing sulfur and nitrogen to crops

‌6. Chemical Synthesis‌

• Intermediate in organic reactions, such as synthesizing heptanal butyl mercaptan
