2-sulfanylacetic acid

2-sulfanylacetic acid is an organosulfur compound with the molecular formula C2H4O2S and CAS number 68-11-1. This chemical features both a carboxylic acid group and a thiol (sulfhydryl) group in its structure, giving it unique reactivity. With a molecular weight of 92.12 g/mol, it is classified as a highly hazardous substance due to its acute toxicity and corrosive properties, requiring careful handling in industrial applications.

2-sulfanylacetic acid is typically found as a white to off-white crystalline solid at room temperature. The compound exhibits a characteristic strong, unpleasant sulfur-like odor due to its thiol group. It is highly soluble in water and polar solvents due to its carboxylic acid functionality. The presence of both carboxyl and thiol groups makes it reactive and prone to oxidation, particularly when exposed to air and moisture.

2-sulfanylacetic acid serves as an important intermediate in pharmaceutical synthesis and biochemical research. It is commonly used in the production of various drugs and as a building block for more complex organosulfur compounds. The compound finds applications in analytical chemistry as a reagent and in the synthesis of metal chelating agents. Its dual functional groups make it valuable for creating specialized chemical compounds in research and industrial processes.

2-sulfanylacetic acid requires strict safety protocols due to its corrosive and toxic nature. Essential personal protective equipment includes chemical-resistant gloves, safety goggles, face shields, and protective clothing. Work must be conducted in well-ventilated areas or under fume hoods to prevent inhalation exposure. Avoid direct skin contact and ensure emergency shower facilities are readily accessible. Only trained personnel should handle this substance, following established chemical safety procedures.

2-sulfanylacetic acid must be stored in tightly sealed, corrosion-resistant containers in a cool, dry, well-ventilated area away from heat sources and incompatible materials. Keep away from strong oxidizing agents, bases, and metals that could react with the compound. Storage areas should be equipped with appropriate spill containment and emergency response equipment. Regular container inspection is essential to prevent leakage and maintain product integrity.

Immediate action is critical following exposure to 2-sulfanylacetic acid. For skin contact, immediately flush the affected area with copious amounts of water for at least 15 minutes while removing contaminated clothing. If inhaled, move the person to fresh air immediately. In case of eye contact, rinse thoroughly with water for at least 15 minutes. Seek immediate medical attention for all exposures, as this substance can cause severe burns and systemic toxicity.

2-sulfanylacetic acid disposal must comply with local, national, and international hazardous waste regulations. The substance cannot be disposed of in regular waste streams due to its corrosive and toxic properties. Contact licensed hazardous waste disposal companies for proper treatment and disposal. Small quantities may require neutralization under controlled conditions before disposal. Always consult current waste disposal regulations and safety data sheets for specific disposal requirements in your jurisdiction.

2-sulfanylacetic acid is classified under ADR Class 8 (corrosive substances), Packing Group II, indicating high hazard level for transportation. Packages must meet UN specification standards for corrosive materials and be properly labeled with appropriate hazard markings and documentation. Transportation requires compliance with dangerous goods regulations, including proper packaging, labeling, and documentation. Only certified carriers experienced in handling corrosive chemicals should transport this substance.

2-sulfanylacetic acid is subject to comprehensive chemical regulations including REACH registration requirements in Europe and CLP classification as a dangerous substance. It is not currently listed as a Substance of Very High Concern (SVHC), but its acute toxicity and corrosive properties require strict compliance with occupational safety regulations. Users must maintain safety data sheets, implement risk assessments, and follow workplace exposure limits as mandated by chemical safety legislation.
