| 2,5-Dichlorophenol Usage And Synthesis |
| Chemical Properties | white to light brown crystals | | Uses | 2,5-Dichlorophenol is an intermediates in the manufacture of more complex chemical compounds such as fungicides. | | 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. | | Definition | ChEBI: A dichlorophenol with the chloro substituents at positions 2 and 5. | | Synthesis Reference(s) | Journal of the American Chemical Society, 74, p. 3890, 1952 DOI: 10.1021/ja01135a052 | | General Description | Prisms (from benzene, petroleum ether) or white crystals. Odor threshold 30 μg/L at 68-72°F; 33 μg/L at 86°F. Taste threshold 0.5 μg/L. | | Air & Water Reactions | Insoluble in water. | | Reactivity Profile | 2,5-Dichlorophenol is incompatible with acid chlorides, acid anhydrides and oxidizing agents. | | Fire Hazard | Flash point data for 2,5-Dichlorophenol are not available. 2,5-Dichlorophenol is probably combustible. | | Purification Methods | Crystallise it from ligroin and sublime it in a vacuum or distil it.
