Applications of 18303-04-3
| Industry | Application | Process |
|---|---|---|
| Pharmaceuticals | Used as an amino-protecting reagent for selective protection of amino groups in peptide and drug molecule synthesis | In organic synthesis, reacts with amines to form stable Boc-protected amines; deprotection is achieved under acidic conditions to enable subsequent functional group transformations or coupling reactions |
| Agrochemicals | Used as an intermediate in the synthesis of nitrogen-containing heterocyclic agrochemicals | Participates in constructing biologically active agrochemical molecules containing sulfonamide moieties, providing tunable reaction sites |
| Fine Chemicals | Used as an organic building block for preparing functionalized sulfonamide derivatives | Introduces p-toluenesulfonyl or tert-butoxycarbonyl functional groups via nucleophilic substitution, coupling, or deprotection reactions for material or ligand design |
