General description

Sulfamic acid, a strong inorganic acid, exists in crystalline form. It is stable, non-hygroscopic, odorless, and colorless in dry state, making its commercial packaging and handling convenient.

Application

It can be used as an acidimetric standard for analytical applications.
Sulfamic acid also finds its use as a primary standard in non-aqueous visual, conductometric, and potentiometric titrations.

Features and Benefits

  • Available in a secure glass bottle to ensure its stability for the entire shelf life until opened.
  • High-quality offering accurate titer determinations
  • Accompanied by a detailed certificate of analysis (CoA)

Sulfamate (NHSO(3)(-)) groups are critically important structural elements of the glycosaminoglycans heparin and heparan sulfate (HS). Experimental conditions are presented for detection of the sulfamate (1)H NMR resonances in aqueous solution. NMR spectra reported for N-sulfoglucosamine (GlcNS) and the synthetic

The iron-catalyzed cross-coupling of aryl sulfamates and tosylates has been achieved with primary and secondary alkyl Grignards. This study of iron-catalyzed cross-coupling reactions also examines the isomerization and β-hydride elimination problems that are associated with the use of isopropyl nucleophiles.

Enhanced receptor selectivity: carbonic anhydrase inhibitors are relevant for both cancer diagnosis and therapy. Combining non-radioactive Re compounds with their radioactive (99m)Tc homologs enables the use of identical molecules for therapy and imaging (theragnostic). The syntheses and in vitro evaluation

An intramolecular diamination of acrylates is reported using sulfamates as nitrogen sources. This reaction proceeds under palladium(II) catalysis with copper bromide as oxidant and gives rise to anti-configured 2,3-diamino carboxylates as bicyclic sulfamate derivatives. An aminobrominated intermediate within the diamination

Unnatural α-amino acids containing dithiocarbamate side chains were synthesized by a one-pot reaction of in situ generated dithiocarbamate anions with sulfamidates. A wide range of these anions participated in the highly regio- and stereo-selective ring opening of sulfamidates to produce
