Buffer Grade
Potassium Acid Phthalate – KHC₈H₄O₄ | CAS 877-24-7
Product Overview
Potassium Acid Phthalate (KHP) is a white crystalline solid widely used as a primary standard in acid-base titrations due to its high purity, stability, and non-hygroscopic nature. With a known molar mass and consistent composition, KHP enables accurate standardization of aqueous base solutions, particularly sodium hydroxide. It dissolves readily in water to form a mildly acidic solution, making it ideal for calibration and validation procedures in laboratory environments.
Key Industries
- Analytical Chemistry – Used as a primary standard for standardizing basic solutions
- Environmental Testing – Supports accurate titration in alkalinity and acidity analysis
- Pharmaceuticals – Applied in quality control and validation testing procedures
- Food & Beverage – Utilized in titration-based determination of acid/base content
- Academic & Research Labs – Commonly used in teaching acid-base equilibria and standardization techniques
Packaging Options
Potassium Acid Phthalate is available in sealed, moisture-resistant containers to ensure long-term stability. Supplied in various sizes from reagent bottles to bulk quantities, each lot includes a Certificate of Analysis (COA) to support traceability and analytical accuracy.
