Isicelo

I-potassium hydrogen phthalate isetyenziswa kakhulu ekulinganiseni izisombululo ze-sodium hydroxide ezisemgangathweni ngenxa yokuba kulula ukufumana iimveliso ezicocekileyo ngokusebenzisa i-recrystallization, ukungabikho kwamanzi e-crystallization, ukunga-hygroscopicity, ukugcinwa lula, kunye nokulingana okuphezulu; Ingasetyenziselwa ukulinganisa isisombululo se-acetic acid kunye ne-perchloric acid (kusetyenziswa i-methyl violet njengesalathisi).
