- A hydroxyl group (-OH) and three chlorine atoms (-Cl) at the 2, 4, and 6 positions on a benzene ring.
- Symmetrical substitution pattern.
Physical Properties
- Appearance: White to pale yellow crystalline solid.
- Odor: Strong phenolic odor.
Applications
- Chemical Synthesis:
- Precursor for pesticides, herbicides, and disinfectants.
- Intermediate in dyes, pharmaceuticals, and wood preservatives.
- Specialty Chemicals:
- Production of flame retardants and industrial additives.
Safety Considerations ⚠️
- Toxicity:
- Toxic via inhalation, ingestion, or skin contact; causes severe irritation to skin, eyes, and respiratory tract.
- Handling:
- Use PPE (gloves, goggles, respirator) and work in a well-ventilated area.
- Storage:
- Store in a cool, dry place away from heat and incompatible materials (e.g., strong oxidizers).
Summary:
2,4,6-Trichlorophenol’s chlorinated phenolic structure drives its use in agrochemicals, disinfectants, and industrial chemicals. Its symmetrical reactivity supports diverse syntheses, but strict safety protocols are critical due to toxicity and irritant hazards.
