Product Overview

Ammonium Sulphate 99% AR/ACS (CAS No. 7783-20-2) is an inorganic salt that dissociates in aqueous media to provide ammonium and sulphate ions. Its solutions exhibit mildly acidic behaviour due to the ammonium component, while the salt’s high ionic contribution makes it useful for establishing defined solution conditions, studying sulphate reactions, and reducing the solubility of suitable macromolecules through salting-out.

The AR/ACS grade is intended for analytical reagent preparation, quality-control testing, research, and academic laboratory procedures requiring controlled composition and restricted reagent-derived impurities. It is suitable for preparing ammonium- and sulphate-containing analytical solutions, adjusting ionic strength, and conducting precipitation, fractionation, and solution-chemistry procedures where consistent reagent quality is important.

Typical Applications

• Preparation of ammonium and sulphate analytical solutions
• Qualitative and quantitative studies involving sulphate ions
• Adjustment of ionic strength in aqueous analytical systems
• Salting-out and fractionation of suitable proteins and macromolecules
• Preparation of selected sulphate salts and double salts
• Crystallisation and solution-equilibrium studies
• Routine analytical, quality-control, and research laboratory work
