In the realm of laboratory chemicals, certain compounds stand out due to their indispensable nature and critical role in ensuring accurate scientific outcomes. Potassium Hydrogen Phthalate (KHP), CAS number 877-24-7, is one such compound, widely acclaimed as a primary standard for analytical chemistry. For R&D scientists and procurement managers, understanding the properties and sourcing of KHP is fundamental to maintaining laboratory integrity. As a dedicated chemical supplier, we aim to provide insight into this essential reagent.

Potassium Hydrogen Phthalate is a white crystalline solid known for its exceptional purity, typically assaying at 99.8% or higher. This high purity, coupled with its non-hygroscopic nature and stability in air, makes it an ideal primary standard. Primary standards are substances of sufficient purity to be used directly to determine the concentration of a solution. In the case of KHP, it is commonly used to standardize basic solutions, such as sodium hydroxide. When you buy KHP, you are acquiring a material that allows for the accurate preparation of standard solutions, which are the backbone of precise titrations and quantitative analyses. Its molecular weight of 204.22 g/mol also contributes to accurate weighing.

Beyond its role as a primary standard, KHP also functions effectively as a buffering agent. It helps maintain a stable pH, particularly in the range of 4.0, which is beneficial for various analytical procedures and biochemical experiments. The low percentage of insoluble matter and trace impurities further enhances its suitability for sensitive applications where contamination could compromise results. This dual functionality makes KHP a versatile and valuable chemical for any laboratory setting.

For laboratories that require a consistent and reliable supply of Potassium Hydrogen Phthalate, choosing the right manufacturer is paramount. A reputable supplier will ensure that each batch of KHP meets stringent quality specifications, backed by a comprehensive Certificate of Analysis. This documentation is crucial for regulatory compliance and for ensuring the reproducibility of experimental data. Sourcing from manufacturers, particularly those in established chemical production regions like China, often provides a competitive advantage in terms of both quality and cost-effectiveness.
