- Mechanism of action
The major mode of action of chlorophenols appears to be the uncoupling of oxidative phosphorylation. The strength of the uncoupling effect is related to the degree of chlorination: PCP is the strongest inhibitor of oxidative phosphorylation, MCP the weakest. To a lesser extent, inhibition of oxidative phosphorylation is affected by the positions of the chlorine atoms on the molecule.

Signs and symptoms in human : When undiluted, it whitens & cauterizes the skin & mucous membranes. 4-chlorophenol was shown to permeate the skin. It produces damage at a threshold concentration of 0.75% (w/v).
Routes of Entry: Absorbed through skin. Eye contact. Toxicity to Animals: Acute oral toxicity (LD50): 367 mg/kg [Mouse]. Acute dermal toxicity (LD50): 1500 mg/kg [Rat]. Chronic Effects on Humans: CARCINOGENIC EFFECTS: Classified 2B (Possible for human.) by IARC. DEVELOPMENTAL TOXICITY: Classified Reproductive system/toxin/male, Development toxin [POSSIBLE]. May cause damage to the following organs: liver, brain, gastrointestinal tract, upper respiratory tract, central nervous system (CNS). Other Toxic Effects on Humans: Very hazardous in case of skin contact (irritant).
