Formic Acid, Potassium Salt (2:1) CAS 20642-05-1
Potassium Diformate cas 20642-05-1 is white crystalline free-flowing powder.
1. Unique double salt structure composed of formic acid and potassium formate; stable under acidic environment, gradually dissociate in neutral/alkaline aqueous system.
2. Easily soluble in water, partial solubility in polar organic solvents; mild acidic property, moderate buffering capacity.
3. Lower volatility compared with pure formic acid, less irritating odor, convenient for storage, transportation and industrial formulation.
4. Excellent thermal stability below decomposition temperature (~120℃); biodegradable, final metabolites are carbon dioxide and water, low residual risk.
5. Broad-spectrum antibacterial performance, effectively inhibit harmful bacteria such as E. coli, Salmonella.
6. High purity grade available, low heavy metal impurity, consistent batch-to-batch quality.
