Description

CAS: 7778-53-2 | K3O4P | 212.265 g/mol

Potassium phosphate is used as a fertilizer and food additive. It serves as a buffering agent to regulate pH. It is also used in optical modulators and for non-linear optics such as second-harmonic generation (SHG). It is involved in the phase-transfer catalyzed preparation of acetylenes from the corresponding vicinal dibromo compounds through double dehydrobromination. It is also useful for the oxidative coupling of thiols to disulfide.

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.
