Description

Ammonium Sulfate is a versatile inorganic salt widely recognized for its high nitrogen and sulfur content. This compound is essential as a highly effective fertilizer, providing crucial nutrients for plant growth and soil health. It serves as a fundamental raw material across diverse global industries, including agriculture, chemical manufacturing, water treatment, and pharmaceuticals.

Application

• Fertilizer & Soil Amendment: A primary source of nitrogen and sulfur for crops, particularly beneficial for alkaline soils.
• Industrial Chemical Synthesis: Used in the production of other ammonium compounds, as a catalyst, and in caprolactam manufacturing.
• Water Treatment & Purification: Acts as a clarifying agent and a nutrient source in biological wastewater treatment processes.
• Food & Beverage Industry: Employed as a dough conditioner and nutrient for yeast in baked goods (food-grade).
• Laboratory & Analytical Chemistry: Utilized in protein purification via precipitation (e.g., ammonium sulfate fractionation) and in buffer solutions.
• Flame Retardants & Textiles: Imparts flame-resistant properties to fabrics and materials.
• Leather Tanning: Serves as a deliming agent in the leather processing industry.

Quality Control

Our Ammonium Sulfate is manufactured under stringent quality management systems. We offer various grades, including technical, agricultural, and food-grade (FCC), each meeting specific industry standards. Certificates of Analysis (COA) documenting purity, assay, and impurity profiles are provided with every shipment to ensure traceability and compliance.

Storage

Preserve in a tightly closed container, protected from light. Store in a cool, dry, and well-ventilated area away from incompatible materials. Due to its hygroscopic nature, the container must be kept tightly sealed to prevent caking from moisture absorption. Recommended storage temperature is between 15°C and 25°C.
