3,5-Dimethylphenol is utilized as a key intermediate in organic synthesis, notably in the production of chloroxylenol (PCMX), a widely used antiseptic and disinfectant with antimicrobial properties. It serves as a building block for phenolic resins, dyes, fragrances, and pharmaceuticals due to its reactive phenolic structure. Additionally, it finds application in agrochemicals and as a precursor for antioxidants and polymer stabilizers, which enhance the oxidative stability and durability of plastics, rubber, and lubricants.
