Description

3,5-Diethylphenol CAS NO 1197-34-8 is a substituted phenol derivative characterized by two ethyl groups in the meta positions relative to the hydroxyl group. This specific substitution pattern makes it a valuable key intermediate and building block in the synthesis of more complex organic molecules, particularly in the production of advanced polymers, antioxidants, and specialty chemicals. It is primarily needed by R&D laboratories, fine chemical manufacturers, and industrial formulators working on high-performance materials, agrochemicals, and pharmaceutical intermediates.

Application

• Polymer Chemistry: As a monomer or chain modifier in the synthesis of phenolic resins, epoxy resins, and polycarbonates to alter thermal and mechanical properties.
• Antioxidant Synthesis: Serving as a crucial precursor for manufacturing sterically hindered phenolic antioxidants used in plastics, rubber, and fuels.
• Agrochemical Intermediates: Used in the production of herbicides, pesticides, and plant growth regulators.
• Pharmaceutical Intermediates: Acting as a building block for active pharmaceutical ingredients (APIs) and other bioactive compounds.
• Dye and Pigment Manufacturing: As an intermediate in the synthesis of complex organic dyes and colorants.
• Lubricant and Fuel Additives: A key component in formulating additives that improve oxidation stability and performance.
• Research & Development: Utilized in academic and industrial R&D for novel material discovery and process development.
• Cross-linking Agents: For specialty coatings and adhesives requiring enhanced durability.
