Description

CAS: 98-74-8 | C6H4ClNO4S | 221.61 g/mol

4-Nitrobenzenesulfonyl chloride is used as an intermediate for the synthesis of pharmaceuticals like foscmprenavir, darunavir and amprenavir. It is involved in the preparation of N-nosyl-alpha-amino acid for peptide synthesis. It is also used for stereoselective α-glucosylation of partially protected carbohydrates in association with silver tri-fluoromethanesulfonate, N,N-dimethylacetamide and triethylamine. It is widely used for the synthesis of hydroxylamines of sulfadiazine, sulfamethoxazole and [Cu(bipy)2Cl](nbs) (1) (bipy = 2,2'-bipyridine, nbs = 4-nitrobenzenesulfonate).

This Thermo Scientific Chemicals brand product was originally part of the Alfa Aesar product portfolio. Some documentation and label information may refer to the legacy brand. The original Alfa Aesar product / item code or SKU reference has not changed as a part of the brand transition to Thermo Scientific Chemicals.
