Potassium Hydrogen phthalate

Product Description

Potassium Hydrogen Phthalate (KHP) is a white crystalline, odorless solid widely recognized as a primary standard in analytical chemistry. Chemically represented as KHC₈H₄O₄, it is a mildly acidic potassium salt of phthalic acid.
KHP is highly stable, non-hygroscopic, and easy to handle — making it ideal for standardizing strong bases in acid-base titrations. It is also used as a buffer component and reference material in pH measurement and analytical research.
