Product Description

Potassium Dihydrogen Orthophosphate (KH₂PO₄) is a high-purity, anhydrous inorganic salt widely used in analytical chemistry, buffer preparation, microbiological media, and laboratory research. It provides a reliable source of potassium ions and phosphate, making it essential for applications requiring precise pH control and ionic balance.

Due to its excellent water solubility and well-defined buffering capacity in the acidic to neutral pH range, KH₂PO₄ is commonly employed in biochemical assays, culture media formulations, and analytical protocols where consistency and reproducibility are critical.

Ausamics Potassium Dihydrogen Orthophosphate is supplied as a free-flowing AR-grade crystalline powder, ensuring dependable performance and batch-to-batch consistency.

Principle of Use

Functional Role

KH₂PO₄ functions as a monobasic phosphate buffer component, providing controlled acidity and ionic strength in aqueous systems. When paired with dibasic phosphates, it enables preparation of phosphate buffer systems across a defined pH range.
