Hazards Summary

Toxicological Profile

Sodium thiomethoxide presents several health hazards that are critical to understand, especially in laboratory and industrial settings where exposure is possible. Research indicates that Sodium thiomethoxide is toxic by ingestion, as evidenced by various studies, including oral lethal-dose experiments in rats. These studies revealed that ingestion could lead to severe systemic effects such as somnolence and dyspnea, alongside other gastrointestinal changes. Additionally, it has been noted that Sodium thiomethoxide can cause corrosive injuries to the upper respiratory tract when inhaled, highlighting its dangerous properties if airborne particles are not adequately controlled. The compound also reacts with water, releasing methanethiol gas, a substance known for its potent and unpleasant odor, which poses additional risks of inhalation exposure.

Specific Organ Toxicity

Further insights into the toxicity of Sodium thiomethoxide come from detailed animal studies, which have shown that exposure to this compound at certain levels, specifically 45 mg/kg/day in rats, leads to significant changes in critical organs. The blood, spleen, and liver are particularly affected, with changes in hematopoiesis and hemosiderosis observed in the spleen and liver. These findings underscore the potential for Sodium thiomethoxide to disrupt normal biological processes in these organs, leading to long-term health complications. Despite these risks, studies have found no evidence of reproductive or developmental toxicity in rats, suggesting that its effects may be more organ-specific rather than systemic reproductive issues. Nevertheless, the severity of its impact on the skin, where it acts as a severe irritant causing burns, further exemplifies the need for stringent safety measures when handling Sodium thiomethoxide. ³
