Applications
Used in high-end foliar sprays and hydroponic solutions where a stable, highly soluble potassium-phosphate source is required.
Utilized as a stabilizer in specialized liquid food formulations where a crystalline handled product is preferred over powder.
Serves as a primary nutrient source and pH regulator in microbial fermentation for the production of enzymes and biopharmaceuticals.
Acts as a stabilizing buffer in parenteral (injectable) drugs and vaccines. It is also used as an excipient in tablet manufacturing.
The preferred form for preparing Phosphate Buffers for HPLC, protein purification, and cell culture media due to its consistent hydration and high purity.
The Trihydrate is significantly less hygroscopic, meaning it won’t “melt” or cake as easily as the anhydrous form, making it much easier to weigh and store.
Yes, our Reagent Grade is purified to ensure ultra-low UV absorbance and minimal metallic impurities.
The specific CAS number is 16788-57-1.
