General description
2,3-Dichloro-1,4-naphthoquinone is a potent and safe fungicide, and finds application in both agriculture and textile industry. During seed treatment, it is used as a foliage spray and is also an excellent mildew-proofing agent. Furthermore it also resists weathering.
Application
2,3-Dichloro-1,4-naphthoquinone was used in its alkaline form in the colorimetric method, used for the spectrophotometric determination of hydrazides. It may also be used for the spectrophotometric analysis of isoniazid in the presence of its hydrazones.
