Product Description
Ammonium sulfate ((NH4)2SO4) is a white crystalline inorganic compound renowned for its high water solubility, finding extensive use in agriculture, industry, and the chemical sector. As a prevalent fertilizer, it comprises around 21% nitrogen and 24% sulfur. Nitrogen is crucial for accelerating the synthesis of plant chlorophyll and promoting stem and leaf growth, while sulfur is indispensable for forming amino acids and enzymes. It is especially suitable for acidic soils and acid-loving crops like potatoes and berries, and can be applied as a granular fertilizer or dissolved in water for foliar spraying.
In industrial settings, it functions as a pH regulator in textile dyeing to enhance dye fixation. In the food industry, categorized as food additive E517, it improves dough texture and supplies nutrients for yeast fermentation. In biochemical research, it enables protein precipitation through salting-out methods. Notably, its aqueous solution shows weak acidity (pH 5.5-6.5). During storage, it must be kept dry to prevent moisture absorption and should avoid contact with strong acids or alkalis. Although non-flammable, high-temperature decomposition may release gaseous by-products, requiring appropriate safety precautions during handling.
Environmentally, long-term excessive use may cause soil acidification, and its nitrogen and sulfur components pose a eutrophication risk when entering water bodies via runoff. Due to its stable chemical properties and dual-nutrient composition, ammonium sulfate remains a fundamental compound in global agricultural production and industrial manufacturing.

Application
Food Industry
Dough Conditioner
Added to flour (e.g., in bread and biscuit production) to enhance gluten extensibility, improve dough gas-holding capacity, and promote yeast fermentation.
Yeast Nutrient
Supplies a nitrogen source for yeast in beer and wine brewing, boosting fermentation efficiency and the formation of flavor compounds.
Acidity Regulator
Used in foods like soy sauce and sauces to adjust flavor and extend shelf-life.
Pharmaceuticals and Biotechnology
Protein Purification
Separates and purifies biological macromolecules (such as enzymes and antibodies) via the "salting-out method" (using high-concentration ammonium sulfate to precipitate proteins), a common technique in biochemical laboratories.
Textile and Dyeing Industry
As a pH regulator, it stabilizes the acidic environment of the dye bath during the dyeing process, enhances the binding force between dyes and fibers (e.g., color fixation for cotton and wool fabrics), and improves dyeing uniformity and color fastness.
Leather Processing
Applied in leather dehairing and softening processes, it adjusts the pH of treatment solutions to promote swelling and softening of leather fibers.
Mineral Processing Industry
Functioning as an inhibitor in the flotation of metal minerals (such as copper and iron ores), it suppresses the floating of gangue minerals to improve concentrate grade.
Electroplating Industry
Used in the preparation of electroplating solutions, it regulates solution conductivity and metal ion deposition rates to enhance coating quality.
It can be applied as base fertilizer, top dressing, or dissolved in water for foliar spraying (e.g., for nutrient supplementation during the growth stages of vegetables and fruit trees).
When combined with organic fertilizers, it helps optimize soil structure and enhance nutrient utilization efficiency.
Packaging & Shipping
Packing: Package in 25/50/1000 bag, also accpet customer OEM packing.
Storage: Keep in a cool, dry, dark location in a tightly sealed container or cylinder.
