3-(5-Nitro-2-furyl)pyrazoles unsubstituted in the 5-position and 5-(5-nitro-2-furyl)pyrazoles unsubstituted in the 3-position are antimicrobials and disinfectants. The compounds are structurally represented by one of the formulae: ##STR1## wherein A is --CHO, --CN, --COOH, a protected or derived aldehyde group or a protected or derived carboxylic acid group; B is 5-nitro-2-furyl; R.sup.1 is --H, substituted or unsubstituted hydrocarbyl (saturated or unsaturated; acyclic, alicyclic or aromatic; or araliphatic); substituted or unsubstituted (cycloaliphatic or aromatic) heterocyclic or acyl (carboxylic or carbonic acid); R.sup.2 is --H; and n is a positive whole number of at most 2.
