Application
1. Alpha-Toluenesulfonyl chloride CAS 1939-99-7 is a crucial organic intermediate for synthesizing sulfa drugs (e.g., antitumor agent E707), enzyme inhibitors, and immunomodulators .
2. Alpha-Toluenesulfonyl chloride functions as a reagent for the protection of amino groups as benzylsulfonamides, which can be cleaved reductively (Na/NH₃) or via photolysis ; it also protects alcohol groups as benzylsulfonates .
3. Applications of Alpha-Toluenesulfonyl chloride extend to serving as an electrophile in palladium-catalyzed reactions (e.g., reductive aminocarbonylation of nitroarenes) and use in cleaners, dyes, and herbicides .
Storage and Precautions
1. Store Alpha-Toluenesulfonyl chloride CAS 1939-99-7 in a tightly sealed container under inert gas (argon) in a cool, dry area; specific temperature recommendations vary (2-8°C, below +30°C, or -20°C under argon) .
2. Keep Alpha-Toluenesulfonyl chloride strictly away from moisture and water, as it decomposes rapidly, releasing toxic and corrosive gases .
3. Always Alpha-Toluenesulfonyl chloride use appropriate personal protective equipment (PPE) including chemical-resistant gloves and eye/face protection; handle only in areas equipped for corrosive solids.
Emergency response to leakage
1. Immediately isolate the spill area; do not generate dust. Contain Alpha-Toluenesulfonyl chloride CAS 1939-99-7 using dry, inert, non-combustible absorbent material and absolutely avoid contact with water .
2. Carefully collect Alpha-Toluenesulfonyl chloride into a sealed, corrosion-resistant chemical waste container for disposal; follow regulations for corrosive solid, acidic, organic, n.o.s..
3. Personnel must wear full chemical-protective equipment; after removal of contaminated clothing, rinse skin with water/shower immediately .
Safety Information
1. Alpha-Toluenesulfonyl chloride CAS 1939-99-7 is corrosive (GHS05, Danger) causing severe skin burns and serious eye damage (H314, H318); inhalation may cause corrosive injuries to the upper respiratory tract and lungs .
2. Alpha-Toluenesulfonyl chloride reacts with water upon contact, decomposes, and requires strict moisture protection; thermal decomposition produces toxic and corrosive fumes including sulfur oxides and hydrogen chloride .
3. Always Alpha-Toluenesulfonyl chloride consult the specific Safety Data Sheet (SDS) for Alpha-Toluenesulfonyl chloride for complete hazard, first-aid, and handling information; precautionary statements.
