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 →Dipotassium phosphate (CAS 7758-11-4), dipotassium hydrogen phosphate, is an inorganic potassium phosphate salt. It is used as a buffering agent, sequestrant, and emulsifying salt, as a corrosion inhibitor in antifreeze systems, and as a nutrient in fermentation and culture media.
Frequently Asked Questions
What is dipotassium phosphate used for?
Dipotassium phosphate (dipotassium hydrogen phosphate) is an inorganic potassium phosphate salt used as a buffering agent and acidity regulator, a sequestrant, an emulsifying salt in processed-cheese systems, a corrosion inhibitor in antifreeze systems, and a potassium/phosphate nutrient in fermentation and culture media.
What is the difference between dipotassium phosphate and monopotassium phosphate?
Dipotassium phosphate (K2HPO4, CAS 7758-11-4) carries two potassium ions and is more alkaline; monopotassium phosphate (KH2PO4) carries one and is more acidic. They are paired to make pH buffers. Confirm the CAS on the CoA for the grade you need.
What is the CAS number and formula of dipotassium phosphate?
CAS 7758-11-4; the anhydrous form is K2HPO4 (listed as HK2O4P). It is the dibasic potassium orthophosphate. Each shipment is supplied with a CoA confirming identity and assay and a current SDS.
What is the HS code for dipotassium phosphate?
Dipotassium phosphate classifies under HS 2835.24 — phosphates of potassium. The CAS is 7758-11-4. Customs documentation and CoA accompany each bulk order.
How is dipotassium phosphate supplied in bulk?
It is typically supplied as a crystalline or granular solid in bags, supersacks, or drums to food, fermentation, and industrial buyers. Available grades and pricing are quote-dependent; submit a bulk RFQ with your quantity for a quote, CoA, and SDS.
