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)

Nitrogen-containing stereotriads, compounds with three adjacent stereodefined carbons, are commonly found in biologically important molecules. However, the preparation of molecules bearing these motifs can be challenging. Herein, we describe a modular oxidation protocol which converts a substituted allene to a

By using DABCO·(SO(2))(2), DABSO, as a solid bench-stable SO(2)-equivalent, the palladium-catalysed aminosulfonylation of aryl-, alkenyl- and heteroaryl halides has been achieved. N,N-Dialkylhydrazines are employed as the N-nucleophiles and provide N-aminosulfonamides as the products in good to excellent yields. The reactions

With years of full-scale experience for precombustion CO(2) capture, amine-based technologies are emerging as the prime contender for postcombustion CO(2) capture. However, concerns for postcombustion applications have focused on the possible contamination of air or drinking water supplies downwind by
