3,4,5-Trichlorophenol(CAS: 609-19-8)

3,4,5-Trichlorophenol is a white or nearly white crystalline solid with a molecular weight of approximately 216.04 g/mol. It has a low solubility in water but is more soluble in organic solvents. The compound shows limited reactivity, primarily undergoing substitution reactions. It is stable under normal conditions but can react with strong reducing agents.

3,4,5-Trichlorophenol is typically synthesized by the chlorination of phenol in the presence of a Lewis acid catalyst, such as aluminum chloride. The reaction is carried out in an organic solvent, and it yields the target compound with reasonable selectivity and good yield under optimized conditions.

3,4,5-Trichlorophenol finds applications in various industries, including pharmaceuticals, where it is used as an intermediate or for its antimicrobial properties. It is also utilized in the production of dyes and organic pigments, and as a precursor in the synthesis of other chlorinated phenols.

When handling 3,4,5-Trichlorophenol, safety goggles, gloves, and lab coats should be worn to protect against potential skin contact and inhalation. It should be stored in a cool, dry place away from heat and ignition sources. In case of a spill, it should be handled in a fume hood with appropriate absorbent materials, and the area should be well-ventilated. The Safety Data Sheet (SDS) should always be consulted for detailed handling and disposal instructions.
