2-Chloro-5-nitrobenzenesulphonyl chloride - Reference Information

EPA chemical information Information provided by: ofmpub.epa.gov (external link)
Introduction 2-chloro-5-nitrobenzenesulfonyl chloride is a derivative of aromatic hydrocarbons, because its functional group contains nitro, halogen and sulfonyl chloride, It can easily react with other compounds, so 2-chloro-5-nitrobenzenesulfonyl chloride is a very important organic intermediate for the preparation of fine chemicals and APIs.
prepare 250ml three-mouth bottle add hydrochloric acid (100mL) and 2-chloro -5-nitroaniline (10g), stir and dissolve, cool down to about 0 ℃, slowly add sodium nitrite aqueous solution (6.0g in 50mL of water), and stir at 0 ℃ for 1 hour after dropping. The obtained diazonium ion solution was then slowly added to an ice bath cooling mixture of copper chloride dihydrate (5g) in acetic acid (500mL) presaturated with sulfur dioxide gas, the reaction mixture was stirred at 0°C for 1 hour, and then slowly added in batches to the ice water under vigorous stirring. Filter and collect the separated solid, rinse with water, and dry under vacuum to obtain the required product 37, cream powder (8.2g,55%).
Use Used as an intermediate in medicine and dyes
