<unk>  <unk> ,4-DCP) is a chlorinated derivative of phenol with the molecular formula C6H4Cl2O. <unk> ,4-DCP is used primarily as an intermediate in the preparation of the herbicide<unk> yacetic acid <unk> ,4-D).  Annual worldwide production is estimated at 88 million pounds. It is also a photo-degradation product of the common antibacterial and antifungal agent triclosan along with the dioxin<unk> ,8-dichlorodibenzo-p-dioxin.
Liquid (molten)<unk> ,4-DCP is readily absorbed through the skin and contact with large amounts may be fatal. Solid<unk> ,4-DCP does not readily absorb through skin and has a lower NFPA H=3 rating (versus H=4 for molten<unk> ,4-DCP). This is primarily caused by instantaneous renal failure, liver damage and various other organ failure.
