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.
3-(5-硝基-2-呋喃基)吡唑在5位未被取代,5-(5-硝基-2-呋喃基)吡唑在3位未被取代时,具有抗微生物和消毒剂作用。该化合物的结构式如下:其中A为--CHO,--CN,--COOH,受保护或衍生的醛基或受保护或衍生的羧酸基;B为5-硝基-2-呋喃基;R.sup.1为--H,取代或未取代的烃基(饱和或不饱和;非环烷基、环烷基或芳香族烃基;或芳基烷基);取代或未取代的(环烷基或芳香族)杂环基或酰基(羧酸或碳酸);R.sup.2为--H;n为最多为2的正整数。
