Sodium Thiosulfate serves as a critical cyanide antidote, playing a life-saving role in medical emergencies and laboratory safety. Its detoxification mechanism is based on a classic metabolic pathway: catalyzed by enzymes, Sodium Thiosulfate acts as a sulfur donor, reacting with cyanide ions to form relatively non-toxic thiocyanate, which is then rapidly excreted in urine. This reaction perfectly complements the first-aid steps involving sodium nitrite or amyl nitrite. The nitrites generate methemoglobin, which preferentially binds with cyanide ions to form cyanmethemoglobin, pulling cyanide away from cytochrome oxidase. Subsequently, Sodium Thiosulfate reacts with these "captured" cyanide ions to achieve complete detoxification. Our eco-grade Sodium Thiosulfate is produced under strict pharmaceutical and reagent standards, featuring extremely high purity and tightly controlled impurity levels, ensuring absolute safety for intravenous use or laboratory applications. In laboratories, it is also used to treat cyanide-containing waste liquid, converting highly toxic cyanide into less toxic thiocyanate via a similar chemical reaction, complying with environmental discharge standards. Therefore, this product is not only an essential standby in emergency kits for potential cyanide poisoning incidents but also a necessary safety reagent in chemical and metallurgical laboratories, embodying the dual value of chemicals in protecting human health and environmental safety.
