Description

CAS: 877-24-7 | C8H5KO4 | 204.222 g/mol

Potassium hydrogen phthalate is used as a primary standard for acid- base titrations as well as for calibrating pH meters and for the preparation of volumetric alkali solutions. It acts as buffer in pH determination. It finds application as a useful standard for total organic carbon testing.

This Thermo Scientific Chemicals brand product was originally part of the Alfa Aesar product portfolio. Some documentation and label information may refer to the legacy brand. The original Alfa Aesar product / item code or SKU reference has not changed as a part of the brand transition to Thermo Scientific Chemicals.
