Potassium Hydrogen Phthalate, Acidimetric Standard, Crystal, Reagent Special, ACS is used in analytical chemistry as a disintegrating agent can be used as a buffering agent (in combination with hydrochloric acid (HCl) or sodium hydroxide (NaOH). As an ACS grade Reagent, Spectrum Chemical manufactured Potassium Hydrogen Sulfate is used as the quality standard against which other Potassium Hydrogen Sulfate substances are graded. it has met the toughest regulatory standards for quality and pureness.
