Product Details
Introduction and Application
4-Isopropyl Benzensulfonyl Chloride, chemical formula C₉H₁₁ClO₂S, CAS number 54997-90-9, molecular weight 218.700. At room temperature, it is a transparent yellow to orange liquid with a density of 1.22 g/cm³ (25°C), a boiling point of 282.6 ± 19.0°C (760 mmHg), and a flash point of 124.7 ± 21.5°C. It has skin corrosiveness (Class 1B) and severe eye damage (Class 1); belongs to the GHS05 hazard category; and has hazard declaration H314.
This substance is mainly used as a pharmaceutical intermediate, with a product purity of ≥ 98-99%, free acid content ≤ 0.5%, and heavy metal content ≤ 0.001% (calculated as Pb). It needs to be sealed and stored in a cool and dry environment, avoiding contact with strong oxidants. Leakage disposal requires wearing N100/P3-type protective equipment, and UN number 3265 (hazard category 8, packaging level II) should be used during transportation. Prepared by chlorination with isopropylbenzenesulfonic acid, the yield is about 61%-94%, which poses a slight hazard to water bodies.
