Ethyl 3-bromo-5-sulfamoylbenzoate is a brominated sulfamoyl benzoate ester with applications in pharmaceutical and agrochemical synthesis. The compound features a reactive bromo substituent at the 3-position and a sulfamoyl group at the 5-position, enabling further functionalization via cross-coupling or nucleophilic substitution reactions. The ethyl ester moiety enhances solubility in organic solvents, facilitating its use in synthetic transformations. This intermediate is particularly valuable in the development of bioactive molecules due to its dual functionality, allowing for selective modifications. High purity and stability under standard conditions make it a reliable building block for research and industrial applications.
