1-Butanesulfonyl Chloride CAS 2386-60-9

1. 1-Butanesulfonyl chloride CAS 2386-60-9 is primarily used as a butanesulfonylating agent and intermediate in the synthesis of pharmaceuticals and agrochemicals.
2. 1-Butanesulfonyl chloride serves as a versatile reagent for introducing the butanesulfonyl group into organic molecules, such as in the preparation of sulfonamides or sulfonate esters.
3. This compound is also utilized in polymer chemistry and materials science.

1. Store 1-butanesulfonyl chloride CAS 2386-60-9 in a cool, dry, well-ventilated place, away from heat, moisture, and incompatible materials (water, alcohols, bases, oxidizing agents). Use airtight containers.
2. Keep the container tightly sealed and clearly labeled. Handle and open containers in a dry environment to prevent violent hydrolysis.
3. Handle 1-Butanesulfonyl chloride with extreme caution using appropriate personal protective equipment (PPE): chemical-resistant gloves, safety goggles, face shield, and an acid-resistant lab coat. Always use a fume hood.

1. Immediately isolate the area, ensure ventilation, and wear full protective gear (gloves, goggles, protective clothing, respirator suitable for acid/organic vapors).
2. **Do NOT use water.** Carefully cover 1-Butanesulfonyl chloride or contain the spill with an inert, dry absorbent material (e.g., sand, vermiculite). Place all contaminated material in a sealed, labeled hazardous waste container.
3. Prevent the compound from entering drains, sewers, or the environment. Decontaminate tools and surfaces with a dry inert material first. Seek expert assistance for cleanup.

1. 1-Butanesulfonyl chloride CAS 2386-60-9 is **highly corrosive, moisture-sensitive, and a lachrymator**. It causes severe skin burns, eye damage, and respiratory damage. 1-Butanesulfonyl chloride is harmful if swallowed or inhaled. Reacts violently with water, alcohols, and bases, releasing heat and toxic/corrosive gases (hydrogen chloride, sulfur dioxide).
2. 1-Butanesulfonyl chloride is flammable and may emit highly toxic and corrosive fumes (hydrogen chloride, sulfur oxides, phosgene) when heated to decomposition.
3. Always consult the official 1-butanesulfonyl chloride Safety Data Sheet (SDS) and handle it as a severe health, corrosion, and reactivity hazard. Specialized training and procedures for sulfonyl chlorides are required.
