1 3-Propanesultone CAS 1120-71-4

1. 1,3-Propanesultone is primarily used as a key sulfonation and sulfopropylation agent in the synthesis of specialty surfactants, zwitterionic compounds, and functional monomers for polymers.
2. 1,3-Propanesultone 1120-71-4 serves as an important intermediate in the production of betaine-type amphoteric surfactants and sulfobetaine polymers with applications in personal care and enhanced oil recovery.
3. 1,3-Propanesultone functions as a chemical building block in pharmaceutical and agrochemical research for introducing sulfopropyl groups into target molecules.

1. Store 1,3-propanesultone in a cool, dry, well-ventilated, and dedicated area, under an inert atmosphere (e.g., nitrogen), in tightly sealed, corrosion-resistant containers protected from moisture and heat.
2. Keep 1,3-propanesultone 1120-71-4 strictly separate from strong bases, nucleophiles, oxidizing agents, and incompatible materials to prevent violent polymerization or hazardous reactions.
3. Handle 1,3-propanesultone with extreme care using non-sparking tools and grounded equipment; ensure containers are clearly labeled as toxic and carcinogenic, and store in a secured, temperature-controlled environment.

1. Immediately evacuate and isolate the spill area, eliminate all ignition sources, and ensure forced ventilation; trained personnel in full protective gear must perform cleanup.
2. Carefully 1120-71-4 contain the spill using inert, non-combustible absorbent materials (e.g., sand, vermiculite); collect all contaminated material into sealed, labeled containers for disposal as highly toxic and carcinogenic waste.
3. Decontaminate the area with a suitable neutralizing or degrading agent (e.g., sodium hydroxide solution for hydrolysis) under controlled conditions, followed by thorough washing; all cleanup waste must be treated and disposed of in full compliance with stringent local, national, and international regulations for carcinogenic substances.

1. 1,3-Propanesultone is a known carcinogen (IARC Group 2A) and may cause cancer through inhalation, skin contact, or ingestion; it causes severe skin burns, eye damage, and respiratory tract irritation.
2. 1,3-Propanesultone 1120-71-4 is highly toxic and may cause damage to organs (e.g., liver, kidneys) through acute or repeated exposure; it is also a mutagen and may cause genetic defects.
3. Always handle 1,3-propanesultone in a certified fume hood or closed system with strict engineering controls, wearing appropriate PPE including full-body protective clothing, chemical-resistant gloves, face shield, and supplied-air respiratory protection.
