Description
Dipotassium phosphate, a reagent celebrated for its exceptional buffering capacity, presents as a stable, hygroscopic, white crystalline powder with remarkable water solubility. Known also as dipotassium hydrogen phosphate trihydrate and identified by CAS number 16788-57-1, it stands out for its chemical robustness. Its notable melting point and density contribute to its versatility in rigorous applications, while its adherence to stringent purity and performance standards assures its dependability and efficacy across various uses.
Specification: Appearance: White crystal or amorphous white powder Assay(dry basis): 98% (as K2HPO4 ) Loss on drying: 2.0% max. Fluoride: 10 ppm max. Insolubles: 0.2 max. Heavy metals [Pb]: 2ppm max. Arsenic [As2O3]: 3ppm max.
Key Features: 1) Versatility: Suitable for a broad range of applications, from food additive to industrial buffer. 2) Solubility: Exceptional water solubility and slight alcohol solubility facilitate diverse applications. 3) Alkalinity: Slightly alkaline in aqueous solutions, beneficial for various chemical processes. 4) Hygroscopic Nature: Absorbs moisture from the air, which can be advantageous in controlled environments.
Applications: In the food industry, Dipotassium Phosphate Anhydrous is employed as a fermentation aid, flavor enhancer, leavening agent, and buffer. Its mild alkaline properties make it particularly useful in dairy products. Industrially, it serves as a buffering agent, culture medium enhancer, and a flavoring agent in synthetic sake production. Additionally, it is a key raw material in the preparation of potassium metaphosphate. In agriculture, it is valued as a high-efficiency phosphorus-potassium compound fertilizer, contributing to the nutrient density of soil.
