Description
POTASSIUM DIFORMATE (KDF)
Crystalline Powder & Granules | IP • BP • USP • LR • AR Grades
Potassium Diformate (KDF) is a double salt composed of potassium formate and formic acid, also known as Potassium Hydrogen Diformate or Potassium Bis(formate). It is a white, crystalline powder or granules with a faint formic acid odour that is freely soluble in water and exhibits a mildly acidic pH in solution. Aaru Life Science supplies Potassium Diformate in multiple pharmacopoeial and laboratory grades including IP, BP, USP, LR, and AR, ensuring suitability across a wide range of pharmaceutical, animal nutrition, food, analytical, and industrial applications. Each batch is manufactured under strict quality control and is compliant with the respective pharmacopoeial standards, making it a reliable choice for formulators, researchers, and industrial users alike.
