Ammonium Sulphamate AR -100g

Ammonium sulfamate is a white, crystalline salt of sulfamic acid supplied here in Analytical‑Reagent (AR) grade. Its combination of high purity, good water solubility and mild acidity makes it useful as a laboratory reagent, descaling agent and, in research settings, as a herbicidal reference compound.
