Potassium formate is an inorganic salt (HCOOK) widely used as a de-icing agent, concrete accelerator, and heat-transfer fluid in secondary cooling systems. It is also employed in oil recovery, textile processing, and as a buffer in chemical synthesis. It is also an ingredient in agricultural fungicide and bactericide formulations, and acts as a reducing agent and antioxidant in oil drilling fluids. CAS 590-29-4, molecular weight 84.12 g/mol, stable at ambient storage conditions with a signal word warning for hazards. Molekula supplies potassium formate from research to bulk quantities with full documentation and ISO 9001:2015 traceability.
