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)

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
