Request SDS →Potassium citrate (CAS 6100-05-6) is tripotassium citrate monohydrate, the potassium salt of citric acid. Established uses include acidity regulation and buffering, sequestrant and chelating duty, and stabilizer and emulsifying-salt function in food and beverage applications. It also serves as a chemical intermediate.
Frequently Asked Questions
What is potassium citrate used for?
Potassium citrate (CAS 6100-05-6) is tripotassium citrate monohydrate, the potassium salt of citric acid. In industrial food and beverage manufacturing it is used as an acidity regulator and buffer, as a sequestrant/chelating agent that binds metal ions to stabilize formulations, and as an emulsifying salt. It also functions as a chemical intermediate.
What is potassium citrate USP/FCC grade?
USP (United States Pharmacopeia) and FCC (Food Chemicals Codex) are compendial specifications that define identity, assay, and impurity limits for the material. Our FG (food grade) USP/FCC potassium citrate is supplied to manufacturers requiring documented compliance with those monographs, with a Certificate of Analysis per lot.
Is the monohydrate grade different from anhydrous potassium citrate?
Yes. This grade is tripotassium citrate monohydrate (CAS 6100-05-6, formula C6H7K3O8), which carries one water of crystallization. The anhydrous form is a separate material (CAS 866-84-2). Specify which CAS you require so we quote the correct grade for your formulation.
What HS code applies to potassium citrate for import?
Potassium citrate classifies under HS 2918.15 — salts and esters of citric acid. We provide the HS code, CoA, and SDS to support customs clearance and import documentation.
What is the cost of bulk potassium citrate?
Bulk pricing depends on grade, packaging (bags, drums, totes), and volume. Request a quote with your target quantity and packaging and we will return current bulk pricing along with the CoA and SDS.
