Maintaining a stable pH is fundamental across a vast spectrum of scientific and industrial processes, from laboratory analysis and pharmaceutical formulations to environmental monitoring. For researchers and product formulators, identifying and sourcing reliable buffering agents is a key task. Potassium Hydrogen Phthalate (KHP), identified by CAS number 877-24-7, is a highly regarded chemical that serves as an effective buffering agent, particularly in the slightly acidic pH range. As a dedicated supplier of specialty chemicals, we emphasize the importance of high-quality KHP for your critical applications.

Potassium Hydrogen Phthalate is a weak acid salt that, when combined with its conjugate base or a strong acid/base, can create buffer solutions with remarkable stability. Its conjugate acid/base pair has a pKa value close to 5.4, making it particularly useful for preparing buffers in the pH range of approximately 4.0 to 5.8. This makes KHP an invaluable tool for analytical chemists, biochemists, and anyone involved in processes requiring precise pH control. For procurement managers, understanding the specific pH buffering capabilities of KHP ensures they are selecting the most appropriate chemical for their needs, often looking for manufacturers who can provide detailed specifications.

The utility of Potassium Hydrogen Phthalate as a buffer extends to various fields. In analytical chemistry, it is frequently used in preparing standard buffer solutions for calibrating pH meters and for use in titration experiments. In biochemistry and molecular biology, maintaining the correct pH is crucial for enzyme activity and sample stability. Pharmaceutical scientists might use KHP in formulation development to ensure drug efficacy and stability. For these applications, sourcing KHP that meets stringent purity standards is non-negotiable. The purity, typically above 99.8%, and low levels of impurities such as chloride, ammonia, and heavy metals are critical indicators of quality.

When considering where to buy Potassium Hydrogen Phthalate, partnering with a reputable manufacturer is key. A reliable supplier will provide comprehensive documentation, including Certificates of Analysis, detailing the chemical’s specifications and lot traceability. This is especially important for R&D scientists who need to ensure the reproducibility of their experiments. Manufacturers based in regions with strong chemical production infrastructure, such as China, often offer competitive pricing and a stable supply chain, making them attractive partners for global businesses.
