Product Overview
Potassium phosphate monobasic BAKER ANALYZED™ ACS reagent is a high-purity crystalline powder designed for demanding laboratory applications where precision and consistency are paramount. This ACS-grade reagent meets stringent analytical standards, ensuring minimal impurities and reliable performance in buffering systems, pH adjustments, and biochemical assays. Its exceptional solubility in water (over 200 g/L at 20°C) allows for rapid dissolution and homogeneous solution preparation, critical for reproducible experimental results. The monobasic form provides a stable pH range when combined with dibasic potassium phosphate, making it ideal for creating phosphate buffer solutions across biological and chemical research. Manufactured under strict quality controls, this reagent offers batch-to-batch consistency with verified composition (KH₂PO₄ with ≥98% purity). The fine particle size distribution enhances handling and weighing accuracy, while the low moisture content (<0.5%) prevents clumping during storage. Compatible with most laboratory glassware and plasticware, it maintains stability under standard lab conditions when stored in tightly sealed containers. The ACS certification guarantees compliance with American Chemical Society specifications, providing researchers with confidence in their experimental outcomes.
FAQs
1. What is the exact chemical formula of this potassium phosphate monobasic?
The chemical formula is KH₂PO₄, representing monopotassium phosphate with one potassium ion, two hydrogen atoms, one phosphorus atom, and four oxygen atoms in its molecular structure.
2. How does the ACS grade differ from technical or reagent grades?
ACS grade meets the highest purity standards set by the American Chemical Society, with stricter limits on impurities like heavy metals (typically <5 ppm for lead, <3 ppm for arsenic) compared to technical or general reagent grades.
3. Can this be used to prepare phosphate-buffered saline (PBS) solutions?
Yes, when combined with dibasic potassium phosphate and sodium chloride in precise ratios, it serves as a key component for PBS preparation, though exact concentrations depend on your specific protocol requirements.
4. What is the typical shelf life when stored properly?
When kept in its original sealed container at room temperature (15-30°C) away from moisture, the product maintains its specified purity for at least 36 months from the date of manufacture.
5. Are there any known incompatibilities with common lab solvents?
It reacts with strong acids to release phosphoric acid and with strong bases to form potassium phosphate salts, but remains stable in aqueous solutions, ethanol mixtures, and most organic solvents at neutral pH.
