Description

Monosodium Phosphate is an essential inorganic salt widely used as a buffering agent, sequestrant, and nutrient source. Its reliable performance in pH control and stabilization makes it a critical component in formulations requiring precise chemical balance. This product is indispensable for manufacturers in the food and beverage, pharmaceutical, water treatment, and industrial cleaning sectors seeking consistent quality and regulatory compliance.

Application

• Food & Beverage Industry: Used as an acidity regulator, emulsifier, and nutrient supplement in processed cheeses, baked goods, and powdered beverages.
• Pharmaceuticals: Serves as a buffering agent in tablet formulations, effervescent products, and electrolyte replenishment solutions.
• Water Treatment: Acts as a corrosion inhibitor and sequestrant in boiler water and cooling tower systems to prevent scale formation.
• Industrial Cleaning: Functions as a builder in detergent and cleaning formulations to enhance efficacy by softening water.
• Animal Feed: Incorporated as a dietary phosphorus supplement for livestock and poultry nutrition.
• Laboratory & Biotechnology: Employed in the preparation of biological buffers for cell culture and molecular biology applications.

Quality Control

Our Monosodium Phosphate is manufactured under a stringent quality management system. It is available in various grades, including Food Grade (FCC), Pharmaceutical Grade (USP), and Technical Grade, each meeting the relevant purity and safety specifications. Certificates of Analysis (COA) documenting key parameters such as assay, heavy metals, and loss on drying are provided with each 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 at room temperature (15-25°C). Due to its hygroscopic (moisture-sensitive) nature, the container must be kept tightly sealed after opening to prevent caking and degradation from atmospheric moisture.
