Formic acid ≥98% is a simple carboxylic acid (HCOOH) widely used as a preservative, coagulant in textile processing, and pH adjuster in chemical synthesis. It also serves as a reducing agent in organic chemistry and is found naturally in some insects’ venom. This reagent-grade formic acid meets ≥98% purity standards with a CAS number of 64-18-6, molecular formula CH₂O₂, and molecular weight of 46.03 g/mol. Store at ambient temperatures; the product carries a **Danger** signal word due to its corrosive and hazardous properties. Molekula supplies formic acid ≥98% from research to bulk quantities with full documentation and ISO 9001:2015 traceability.
