Ammonium Hydrogen Sulfate, identifiable by CAS 7803-63-6, functions as a crystalline acidic salt used primarily as a catalyst in organic synthesis and a flame retardant for cellulosic materials. Chemically defined as Ammonium Bisulfate, this white, hygroscopic solid serves as a precursor for the production of ammonium persulfate and a pH regulator in industrial bleaching processes. The substance, often referred to as Monoammonium Sulfate in technical specifications, acts as a dehydrating agent in chemical manufacturing and a nitrogen-sulfur source in specialized fertilizer formulations. We facilitate bulk supply of this inorganic acid salt with competitive factory pricing, capable of meeting customized specifications for acidity and moisture control, backed by comprehensive MSDS, TDS, COA documentation.

FAQ - Technical & Supply Chain
-
Q:
Is this material suitable for flame retardant applications?
A: Ammonium Hydrogen Sulfate is typically applied as a flame retardant component for paper, wood, and cellulose insulation products due to its ability to release non-flammable gases upon heating. -
Q:
Is Ammonium Hydrogen Sulfate chemically synonymous with Ammonium Bisulfate?
A: Yes, Ammonium Hydrogen Sulfate and Ammonium Bisulfate refer to the same inorganic compound identified by CAS 7803-63-6, representing the half-neutralized salt of sulfuric acid.
