Overview
Chloro thiohypochlorite (CAS 10545-99-0) is an inorganic sulfur-chlorine compound with strong oxidizing and corrosive properties. This chemical compound, with the molecular formula Cl2S and a molar mass of 102.97 g/mol, represents a specialized reactive intermediate in industrial chemistry. As a member of the sulfur-chlorine compound family, chloro thiohypochlorite exhibits unique chemical behavior that makes it valuable for specific industrial applications requiring controlled reactivity. The compound's structure contains both sulfur and chlorine atoms, contributing to its distinctive chemical properties and reactivity profile. The substance is classified under multiple hazard categories, including skin corrosion (Skin Corr. 1B), specific target organ toxicity (STOT SE 3), and acute aquatic toxicity (Aquatic Acute 1). These classifications necessitate careful handling protocols and appropriate safety measures during storage, transportation, and use. The ADR class 8 designation indicates its corrosive nature, requiring specialized packaging and transport conditions to ensure safety and regulatory compliance. In industrial applications, chloro thiohypochlorite serves primarily as a chemical intermediate in synthesis processes, particularly in the production of organosulfur compounds and as a selective chlorinating agent. Its reactivity makes it suitable for specialized organic transformations where controlled introduction of chlorine or sulfur functionalities is required. Unlike compounds such as 3-[[bis(2-ethylhexyl)amino]methyl]-1,3-benzothiazole-2-thione, which serves different industrial purposes, chloro thiohypochlorite's primary value lies in its role as a reactive intermediate rather than as an end-use product. OYSI maintains reliable supply chains for chloro thiohypochlorite, ensuring consistent availability for European industrial customers requiring this specialized chemical intermediate.

The substance is classified under multiple hazard categories including skin corrosion and specific target organ toxicity, indicating its aggressive chemical nature and potential for causing severe chemical burns upon contact.
What is chloro thiohypochlorite used for?
Chloro thiohypochlorite is primarily used as a specialized chemical reagent in industrial processes requiring strong oxidizing or chlorinating agents. Its applications are typically limited to controlled industrial environments due to its highly corrosive nature and significant safety hazards. The compound may be utilized in specific chemical synthesis processes, water treatment applications, or as an intermediate in the production of other sulfur-chlorine compounds, always under strict safety protocols and professional supervision.
How to handle chloro thiohypochlorite safely?
Chloro thiohypochlorite requires extreme caution during handling due to its Skin Corr. 1B classification and DANGER signal word. Essential personal protective equipment includes chemical-resistant gloves, safety goggles, face shields, and protective clothing to prevent skin and eye contact. Work must be conducted in well-ventilated areas or under fume hoods to avoid inhalation. Emergency shower and eyewash stations should be readily accessible, and only trained personnel should handle this substance following strict safety procedures.
How to store chloro thiohypochlorite correctly?
Chloro thiohypochlorite must be stored in a cool, dry, well-ventilated area away from incompatible materials due to its corrosive nature. Storage containers should be made of compatible materials resistant to corrosion and kept tightly sealed to prevent moisture absorption and vapor release. The storage area should be equipped with appropriate spill containment measures and emergency response equipment. Access should be restricted to authorized personnel only, and storage conditions must comply with local chemical safety regulations.
What to do in case of contact with chloro thiohypochlorite?
Chloro thiohypochlorite contact requires immediate emergency response due to its severe corrosive properties.
