Formic acid (90%) is a naturally occurring carboxylic acid with a pungent odor, primarily used in livestock feed as a preservative, in textile dyeing as a mordant, and in leather tanning. It also serves as a coagulant in latex production and a reducing agent in chemical synthesis. This technical-grade acid contains 90% formic acid by weight, with a CAS number of 64-18-6, molecular formula CH₂O₂, and a molecular weight of 46.03 g/mol. It must be stored at ambient temperatures in a well-ventilated area, away from incompatible substances. The product carries a **Danger** signal word due to its corrosive and hazardous nature. Molekula supplies formic acid 90% from research to bulk quantities with full documentation and ISO 9001:2015 traceability.
