Product Description

Chlorobenzene (C6H5Cl) CAS 108-90-7
Chlorobenzene is a colorless, aromatic solvent and chemical intermediate used widely in organic synthesis, dye and pigment manufacture, rubber and polymer processing, and as a feedstock for chlorination chemistries. It is handled as a flammable, volatile organic liquid with characteristic aromatic odor and must be managed under standard industrial hygiene and transport controls.

Applications

  • Solvent for chemical synthesis
    Chlorobenzene is used as a reaction solvent for a variety of aromatic substitution, chlorination and electrophilic processes.
  • Intermediate for agrochemicals and dyes
    Used as a feedstock or intermediate in the manufacture of pesticides, herbicides, dyes and pigment intermediates.
  • Rubber and polymer processing
    Serves as a solvent or processing aid in elastomer compounding, resin formulations and specialty polymer syntheses.
  • Extraction and formulation solvent
    Applied in extraction processes and as a formulation solvent in coatings, adhesives and specialty blends.
  • Analytical reagent and standard
    Used in laboratories as a reference solvent, standard reference material and QC reagent for method development.
