2-sulfanylacetic acid

2-sulfanylacetic acid is an organosulfur compound with the molecular formula C2H4O2S and CAS number 68-11-1. This chemical substance has a molecular weight of 92.12 g/mol and contains both carboxylic acid and thiol functional groups. It is classified as a hazardous substance with high acute toxicity and corrosive properties, requiring careful handling and storage procedures in industrial applications.

2-sulfanylacetic acid is typically a crystalline solid at room temperature with characteristic sulfur-containing compound odor. The substance is highly soluble in water due to its carboxylic acid group and polar nature. It exhibits strong reducing properties due to the presence of the thiol group, making it reactive with oxidizing agents and metals under certain conditions.

2-sulfanylacetic acid serves as an important intermediate in pharmaceutical synthesis and chemical manufacturing. It is commonly used in the production of various medications, particularly as a building block for drug compounds. Additionally, it finds applications in biochemical research, analytical chemistry, and as a reducing agent in specialized chemical processes requiring thiol functionality.

2-sulfanylacetic acid requires strict safety measures due to its Acute Tox. 3 and Skin Corr. 1B classifications. Operators must wear appropriate personal protective equipment including chemical-resistant gloves, safety goggles, and protective clothing. Work should be conducted in well-ventilated areas or under fume hoods to avoid inhalation exposure, and direct skin contact must be prevented at all times.

2-sulfanylacetic acid must be stored in tightly sealed containers in a cool, dry, and well-ventilated area away from heat sources and direct sunlight. The substance should be kept separated from oxidizing agents, bases, and metals to prevent unwanted reactions. Storage areas should be equipped with appropriate containment measures and emergency procedures due to the corrosive nature of the compound.

Immediate action is required for any contact with 2-sulfanylacetic acid due to its corrosive properties. For skin contact, immediately flush the affected area with large amounts of water for at least 15 minutes and remove contaminated clothing. In case of eye contact, rinse thoroughly with water and seek immediate medical attention. If inhaled, move the person to fresh air and consult a physician immediately.

2-sulfanylacetic acid disposal must comply with local and European waste regulations as it is classified as hazardous waste. The substance cannot be disposed of through regular waste streams and requires specialized hazardous waste treatment facilities. Neutralization procedures should only be performed by qualified personnel, and all disposal activities must be documented according to regulatory requirements.

2-sulfanylacetic acid is classified under ADR Class 8 (corrosive substances) Packing Group II, requiring specialized transport procedures. The substance must be packaged in UN-approved containers with appropriate labeling including GHS06 and GHS05 pictograms and 'Danger' signal word. Transport vehicles must carry proper documentation and emergency response information, and drivers require ADR certification for corrosive materials.

2-sulfanylacetic acid is subject to comprehensive European chemical regulations including REACH registration and CLP classification requirements. The substance is not currently listed as an SVHC (Substance of Very High Concern) but must comply with standard chemical safety data sheet provisions, hazard communication requirements, and workplace exposure limits where applicable under occupational health regulations.
