  • Applications

    2,3-Dichlorophenol (CAS 576-24-9) is an important chemical intermediate in industrial synthesis: it is used as a feedstock for agrochemicals (precursor for herbicides and fungicides) and for colorants and dye chemistries. It also serves as a building block for chlorinated phenolic compounds used in coatings and inks, and as a fundamental component for plastic additives and polymer stabilizers. Additionally, it may be used as a precursor for other specialty chemicals in the industrial sector and for surface-treatment formulations.
