Product Overview

Potassium dihydrogen phosphate (KH₂PO₄) from AnalaR NORMAPUR® is a premium ACS reagent-grade chemical designed for high-precision laboratory applications. This crystalline powder offers exceptional purity, meeting both ACS (American Chemical Society) and Ph. Eur. (European Pharmacopoeia) standards, ensuring reliable and reproducible results in critical experiments. Its low impurity profile makes it ideal for buffer solutions, pH calibration, and quantitative analytical procedures where consistency is paramount. The compound’s high solubility in water (22.6 g/100 mL at 20°C) allows for easy preparation of standard solutions, while its stable crystalline structure ensures long-term storage without degradation. The AnalaR NORMAPUR® certification guarantees traceability and batch-to-batch uniformity, minimizing variability in sensitive assays. Its non-hygroscopic nature further enhances handling convenience, reducing moisture absorption risks during weighing or storage. This reagent is particularly valued in spectrophotometry, chromatography, and titration methods due to its precise stoichiometric properties. The absence of heavy metal contaminants (≤5 ppm) and minimal chloride content (≤0.001%) align with stringent lab requirements, making it a preferred choice for research-grade formulations. Whether used as a primary standard or a supporting reagent, this potassium dihydrogen phosphate delivers consistent performance across diverse laboratory protocols.

FAQs

1. What is the solubility of this potassium dihydrogen phosphate in water?

It dissolves readily in water at 22.6 g/100 mL at 20°C, forming a clear, colorless solution suitable for buffer preparation.

2. Can this reagent be used for pH calibration of electrodes?

Yes, its high purity and defined pH in solution (4.01 for 0.025M at 25°C) make it ideal for calibrating pH meters and electrodes.

3. How does this compare to food-grade potassium dihydrogen phosphate?

This ACS reagent grade has stricter purity controls (≤0.001% chloride, ≤5 ppm heavy metals) compared to food-grade versions, which may contain higher impurities.
