Potassium phthalate monobasic may be used as a primary standard in acidimetric titration and also to prepare potassium phthalate buffer solution for pH calibration.

General description

Potassium phthalate monobasic (KHP) is the monopotassium salt of pthalic acid. It has been proposed as a certified reference material (CRM) under ISO/IEC 17025 and ISO Guide 34 accreditation. Its spectral shift, multiplicity, solubility and relaxation times in different solvents have been reported.
