  • Applications

    Ammonium sulfate, ACS reagent is a versatile salt widely used as a nitrogen and sulfur source in agriculture, functioning as a fertilizer and acidifying soil to suit certain crops. In biochemistry laboratories, it is used as a salting-out agent to precipitate and purify proteins. In bioprocessing and fermentation, it serves as a nitrogen source to support microbial growth. In analytical chemistry, it provides sulfate or ammonium ions for analytical procedures and sample preparation, and can act as a salting-out or crystallization aid in preparative work.
