3,5-Dimethylphenol (3,5-xylenol, CAS 108-68-9) is a substituted phenol used as a monomer and synthetic intermediate in specialty polymers, hindered-phenol antioxidant manufacture, resin and adhesive intermediates, and fine-chemical production. Commercial offerings include high-purity reagent grades for R&D and technical/industrial grades for process applications.
Storage & handling
Store in original, tightly closed containers in a cool, dry, well-ventilated area away from heat and strong oxidizers. Protect from moisture and direct sunlight; handle with closed transfer to avoid dust generation. Follow lot SDS for recommended PPE, segregation, spill response and any refrigerated/inert storage instructions for specific grades.
Application
- Monomer for specialty polymers
Used as a monomer/comonomer in oxidative coupling and polymerization routes for specialty engineering resins and high-performance phenolic polymers. - Intermediate for hindered phenolic antioxidants
Serves as a feedstock to synthesize sterically hindered phenolic antioxidants for polymers, lubricants and stabilizer packages. - Resin, adhesive and coating intermediates
Employed in manufacture of phenolic resins, curing agents and specialty crosslinkers used in adhesives and coatings. - Agrochemical and specialty-chemical intermediates
Used as a building block in synthetic routes for select agrochemical intermediates and specialty fine chemicals. - Analytical & laboratory reagent
Provided in small packs for R&D, method development and QC reference standards. - Industrial processing aid / solvent additive
Used in niche process formulations where phenolic reactivity and the 3,5-substitution pattern deliver desired performance.
