Potassium Dihydrogen Phosphate Extra Pure, also known as monopotassium phosphate (MKP), is a white crystalline compound with excellent solubility in water and a slightly acidic pH. It serves as a valuable buffering agent and a source of both potassium and phosphorus in various chemical, agricultural, and food-grade applications. In laboratories, it is commonly used in the preparation of buffer solutions and nutrient media for microbial culture. In agriculture, it is employed as a high-efficiency fertilizer due to its dual nutrient content, promoting strong root development and flowering. This compound should be stored in a cool, dry place, away from incompatible substances and moisture to preserve its purity and effectiveness.

Ammonium Carbonate Extra Pure
Ammonium Carbonate Extra Pure is a high-quality, white crystalline solid widely used across various scientific, industrial, and food-related applications. Manufactured to stringent purity standards, this compound is ideal for laboratories and processes that demand high-grade reagents. With its characteristic ammonia-like odor and ability to decompose upon heating, ammonium carbonate plays a versatile role in both chemical reactions and physical processes.
In aqueous solution, ammonium carbonate breaks down into ammonium bicarbonate and ammonium carbamate, further releasing ammonia (NH₃) and carbon dioxide (CO₂) upon heating. This property makes it especially useful in applications that require controlled gas release or temporary pH modification.
