A grade-specific Safety Data Sheet (SDS) — with the complete hazard classification, handling precautions, and transport information — is supplied with every shipment and available on request. Confirm all safety and regulatory details against the SDS for your specific grade.
Request SDS →Tripotassium phosphate (CAS 7778-53-2) is the tribasic potassium salt of orthophosphoric acid, K3PO4. It functions as an alkaline buffering and pH-regulating agent, as a sequestrant and stabilizer in food applications, and as a source of potassium and phosphate in fertilizer and soil-amendment use. It is also documented as a cleaning agent and corrosion inhibitor.
Frequently Asked Questions
What is tripotassium phosphate used for?
Tripotassium phosphate (K3PO4, CAS 7778-53-2) is the tribasic potassium salt of orthophosphoric acid. It functions as an alkaline buffering and pH-regulating agent, a sequestrant and stabilizer in food processing, a potassium and phosphate source in fertilizers, and is documented in industrial cleaning formulations and as a corrosion inhibitor.
What is the chemical formula of tripotassium phosphate?
The formula is K3PO4 (also written K3O4P). It is the fully neutralized tribasic potassium salt of phosphoric acid and is strongly alkaline in solution.
Is tripotassium phosphate the same as trisodium phosphate?
No. Tripotassium phosphate (K3PO4, CAS 7778-53-2) carries potassium cations, while trisodium phosphate (Na3PO4, CAS 7601-54-9) carries sodium. Both are tribasic orthophosphate salts and alkaline buffers, but they are distinct chemicals with different cations and specifications.
Is tripotassium phosphate available as a monohydrate?
Tripotassium phosphate is documented in both anhydrous and monohydrate forms; the form affects assay and handling. Specify the required form and grade when requesting a quote, and confirm against the CoA for each lot.
How is tripotassium phosphate supplied in bulk?
It is typically supplied as a granular or powder solid (and as solution for some applications) in bags, drums, or bulk depending on grade and volume. Request a bulk quote from RawSource for current packaging, lead time, and SDS/CoA documentation.
