Supplied by Saltigo as a yellowish-to-green liquid at a minimum 98.0% a/a purity in 250 kg drums, N,N-dimethylaminosulfamoyl chloride (DMSC) is a versatile building-block reagent. It acts as a leaving group in transition-metal-catalyzed cross-couplings and nucleophilic displacements, activates carboxylic acids for ester formation and peptide coupling, protects NH-acidic positions, serves as an electrophilic chlorinating agent for organometallic intermediates, and functions as an ortho-directing group in C-H deprotonation.
