Sulfurochloridic acid

Sulfurochloridic acid is a highly corrosive inorganic chemical compound with the molecular formula ClHO3S and CAS number 7790-94-5. This dangerous substance has a molecular weight of 116.53 g/mol and is classified as a skin corrosive category 1A material. It poses significant health hazards and requires careful handling due to its corrosive properties that can cause severe skin and eye damage upon contact.

Sulfurochloridic acid is a liquid chemical compound that typically appears as a colorless to pale yellow solution. It has strong acidic properties and is highly reactive with water, releasing heat and corrosive vapors. The substance is highly soluble in water and polar solvents, forming highly acidic solutions. It has a pungent, irritating odor and decomposes under certain conditions, making proper ventilation essential during handling.

Sulfurochloridic acid is primarily used as a chemical intermediate in various industrial processes and chemical synthesis applications. It serves as a reagent in organic chemistry reactions, particularly in sulfonation processes and the production of other sulfur-containing compounds. The substance is also utilized in specialized manufacturing processes where its strong acidic and reactive properties are required for specific chemical transformations.

Sulfurochloridic acid requires strict safety protocols including full personal protective equipment: acid-resistant gloves, safety goggles, face shield, and chemical-resistant clothing. Work must be conducted in well-ventilated areas or under fume hoods to avoid inhalation of vapors. Avoid contact with skin, eyes, and clothing. Keep emergency eyewash stations and safety showers nearby. Never add water directly to the acid to prevent violent reactions.

Sulfurochloridic 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 bases, metals, and organic materials that may react violently. Storage areas should be equipped with secondary containment systems and spill cleanup materials. Ensure proper labeling and restrict access to authorized personnel only.

Immediate action is critical for sulfurochloridic acid exposure. For skin contact, remove contaminated clothing and flush affected area with large amounts of water for at least 15 minutes. For eye contact, rinse immediately with water for 15-20 minutes while holding eyelids open. If inhaled, move to fresh air immediately. Seek immediate medical attention for all exposures. Do not induce vomiting if swallowed.

Sulfurochloridic acid disposal must comply with local and international hazardous waste regulations. The substance cannot be disposed of in regular waste streams due to its corrosive nature. Neutralization should only be performed by trained professionals using appropriate techniques and equipment. Contact licensed hazardous waste disposal companies for proper collection and treatment. Maintain detailed disposal records as required by regulations.

Sulfurochloridic acid is classified as ADR Class 8 (corrosive substances) Packing Group I, indicating maximum danger level for transport. It requires specialized packaging meeting UN specifications, proper labeling with corrosive hazard symbols, and transport documentation. Only certified carriers trained in hazardous materials transport should handle shipments. Emergency response information must accompany all shipments for accident scenarios.

Sulfurochloridic acid is regulated under multiple European frameworks including REACH registration requirements and CLP classification as a corrosive substance with danger signal word. It carries GHS pictograms GHS05 and GHS07, indicating corrosive and harmful properties. The substance is not currently listed as SVHC under REACH, but users must comply with safety data sheet requirements and workplace exposure limits where established.

Sulfurochloridic acid is available through specialized chemical distributors across Europe, including OYSI, which supplies high-quality chemical products to industrial customers throughout the European market. Due to its hazardous nature, purchases typically require proper business credentials, safety certifications, and compliance with local regulations. Contact authorized distributors like OYSI for availability, specifications, and regulatory compliance support for your specific applications.
