formic acid

 [for´mik]
a colorless, pungent liquid with vesicant properties, from nettles and ants and other insects; derivable from oxalic acid and from glycerin and from the oxidation of formaldehyde.

for·mic ac·id

(fōr'ik as'id),
HCOOH; the smallest carboxylic acid; a strong caustic, used as an astringent and counterirritant.

formic acid

/for·mic ac·id/ (for´mik) an acid from the distillation of ants and derivable from oxalic acid and glycerin and from the oxidation of formaldehyde; its actions resemble those of acetic acid but it is much more irritating, pungent, and caustic to the skin. The acid and its sodium and calcium salts are used as food preservatives.

formic acid (HCOOH)

[fôr′mik]
a colorless, pungent liquid found in nature in nettles, ants, and other insects. It is prepared commercially from oxalic acid and glycerin and from the oxidation of formaldehyde. Formerly used as a vesicant, it currently has no therapeutic applications. Also called methanoic acid.

formic acid (methanoic acid)

a colourless, corrosive, fuming liquid with a pungent smell. It occurs in ants and in certain plants and is the simplest of the CARBOXYLIC ACIDS. Formula: HCOOH.
