Chemical Properties
white to light brown crystals
Uses
2,5-Dichlorophenol may be used as an analytical reference standard for the determination of the analyte in water, and wood, paper, cardboard, fruits, and fruit juices using simultaneous dispersive liquid-liquid microextraction and derivatization followed by gas chromatography-electron-capture detection (GC-ECD) and gas chromatography-mass spectrometry (GC-MS), respectively.
Uses
2,5-Dichlorophenol is an intermediates in the manufacture of more complex chemical compounds such as fungicides.
