Useful:

• Chemical Composition and Structure: 4-Chloro-2-fluoro-5-sulfamoylbenzoic acid belongs to the category of pharmaceutical materials and typically has a purity of 98%.
• Uses and Mechanism of Action: Furosemide, derived from 4-Chloro-2-fluoro-5-sulfamoylbenzoic acid, is a diuretic sulfonamide used in the treatment of conditions such as edema and hypertension. It acts as an inhibitor of urine dilution and concentration, providing rapid diuresis. 4-Chloro-2-fluoro-5-sulfamoylbenzoic acid serves as a key intermediate in the synthesis of furosemide, facilitating the condensation reaction with furfurylamine to produce the desired pharmaceutical product.
• Production Methods: The synthesis of 4-Chloro-2-fluoro-5-sulfamoylbenzoic acid involves a multi-step process, including photochlorination of 4-chloro-2-fluoro-toluene to obtain 4-chloro-2-fluoro-benzotrichloride, chlorosulfonylation of the latter, and subsequent ammonolysis to yield the target compound.
