It is a colorless, fuming liquid with a pungent, irritating odor, highly miscible with water, ethanol, and ether. Naturally occurring in the venom of ants and stinging nettles, formic acid is a versatile chemical raw material with strong reducing properties and corrosivity, widely used in industrial, agricultural, and pharmaceutical fields.

Key Applications

Leather & Textile Industry: Used as a tanning agent for leather processing to improve softness and durability; serves as a dyeing auxiliary for textiles, enhancing dye penetration and color fastness.

Agriculture & Animal Husbandry: Applied as a preservative and antibacterial agent for feed; used in silage production to inhibit the growth of spoilage microorganisms and extend storage time. Also acts as a herbicide and insecticide intermediate.

Chemical Synthesis: A key raw material for producing formate esters (e.g., methyl formate, ethyl formate), formamide, and oxalic acid. Used in the synthesis of pharmaceuticals, pesticides, and surfactants.

Deicing & Cleaning: Mixed with other reagents to make deicing fluids for aircraft and roads (low corrosivity to metals); used as a descaling agent for industrial boilers and pipelines.

Laboratory & Analytical Chemistry: Serves as a reducing agent and acid catalyst in organic synthesis; used in gas chromatography as a mobile phase additive.
