Description

2,3,5,6-Tetrachlorophenol CAS NO 935-95-5 is a halogenated phenolic compound characterized by its four chlorine substituents on the aromatic ring. This specific chlorination pattern makes it a valuable intermediate and functional chemical in several high-value industrial synthesis processes. It is primarily sought after by manufacturers in the agrochemical and specialty chemical sectors for its role in producing advanced materials and active ingredients.

Application

• Agrochemical Intermediate: A key precursor in the synthesis of certain herbicides, fungicides, and wood preservatives, leveraging its phenolic and halogenated structure.
• Pharmaceutical Synthesis: Serves as a building block for creating complex molecules in active pharmaceutical ingredient (API) development.
• Dye and Pigment Manufacturing: Used in the production of specific halogenated dyes and colorants.
• Polymer Additive: Acts as a monomer or modifying agent in the synthesis of specialty polymers with enhanced flame-retardant or stability properties.
• Research & Development: Employed in chemical research as a standard or reagent for studying chlorophenol chemistry and environmental fate.
• Preservative Formulation: Finds use in the formulation of industrial preservatives and biocides.
