Description

Potassium Hydrogen Phosphate(V) CAS NO 7758-11-4 is a high-purity inorganic salt, also known as dipotassium hydrogen phosphate, widely used as a buffering agent and nutrient source. Its consistent quality and high solubility make it a critical component for maintaining precise pH levels and ionic strength in sensitive formulations. This product is essential for manufacturers in the pharmaceutical, food & beverage, and industrial biotechnology sectors who require reliable, specification-grade raw materials for their production processes.

Application

• Pharmaceutical Buffer & Excipient: Used in the formulation of injectables, ophthalmics, and oral solutions to maintain physiological pH.
• Food Additive (E340(ii)): Acts as an emulsifier, stabilizer, and pH regulator in processed foods, dairy products, and beverages.
• Microbiological Culture Media: Serves as a source of phosphorus and potassium in nutrient broths and agars for cell culture and fermentation.
• Industrial Water Treatment: Functions as a corrosion inhibitor and scale prevention agent in boiler water and cooling systems.
• Fertilizer & Agricultural Solutions: Provides a highly soluble source of potassium and phosphorus in liquid fertilizers and hydroponic nutrient solutions.
• Analytical Chemistry & Reagents: Used in the preparation of standard buffers for laboratory calibration and analytical procedures.
• Detergent & Cleaning Formulations: Enhances cleaning efficiency by sequestering metal ions and aiding in soil suspension.

Quality Control

Our Potassium Hydrogen Phosphate(V) is manufactured under a strict quality management system. We offer grades compliant with USP-NF, FCC, and ACS standards, ensuring suitability for food, pharmaceutical, and high-purity laboratory applications. Every batch is supported by a comprehensive Certificate of Analysis (COA) detailing purity, identity, and impurity profiles, guaranteeing traceability and consistency for your critical processes.

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). This material is hygroscopic (moisture-sensitive); the original container must be kept tightly sealed to prevent caking and degradation due to absorption of atmospheric moisture.
