Potassium phthalate ACS is observed in the form of colorless or white crystals or crystalline powder. Its chemical formula is C8H5KO4. It is also referred to as Potassium hydrogen phthalate, Potassium biphthalate, KHP, Phthalic Acid Monopotassium Salt, and Phthalic acid potassium salt. This compound is slightly soluble in water under normal conditions. Upon decomposition due to heating, it releases oxides of carbon like Carbon monoxide (CO) and Carbon dioxide (CO2). Widely used in analytical chemistry, Potassium phthalate ACS serves as a primary standard for the standardization of strong acids. ACS grade signifies that the substance complies with the standards established by the American Chemical Society, guaranteeing high purity and quality suitable for laboratory and analytical purposes. Potassium phthalate ACS grade is a valuable asset in analytical chemistry due to its precision, user-friendliness, versatility, and reliability in the standardization of strong acids and maintenance of pH stability in various laboratory settings.

ChemieR provides an extensive selection of high-purity salts, acids, base and high purity solvents, including alkali metals, alkaline earth compounds, perchlorates, heavy metals, rare earths, transition metals, silver and precious metals, and triflates. ChemieR specialize in inorganic chemicals, offering materials with low moisture content and minimal trace metals. ChemieR stands out with a diverse range of laboratory chemicals, from organic and inorganic reagents to solvents.
