Description

Trimethylphenol CAS NO 26998-80-1 is a versatile alkylated phenol derivative, serving as a crucial intermediate in the synthesis of high-performance antioxidants and polymer stabilizers. Its value lies in its ability to impart excellent oxidative and thermal stability to a wide range of industrial materials, protecting them from degradation. This compound is essential for manufacturers in the plastics, rubber, and specialty chemical industries seeking to enhance product longevity and performance under demanding conditions.

Application

• Antioxidant Synthesis: A key precursor for manufacturing phenolic antioxidants like BHT (Butylated Hydroxytoluene) analogs and other hindered phenols used in polymers, fuels, and lubricants.
• Polymer Stabilizers: Used to produce stabilizers that protect plastics (e.g., polyethylene, polypropylene) and synthetic rubbers from oxidative degradation during processing and service life.
• Resin & Adhesive Intermediates: Functions as a building block in the production of modified phenolic resins, epoxy hardeners, and high-performance adhesive formulations.
• Pharmaceutical & Agrochemical Intermediates: Employed in the synthesis of certain active pharmaceutical ingredients (APIs) and agrochemicals due to its reactive phenolic hydroxyl and methyl groups.
• Dye & Pigment Manufacturing: Serves as an intermediate in the production of certain dyes, pigments, and UV absorbers.
• Fuel & Lubricant Additives: Used to develop additives that prevent gum formation and oxidation in gasoline, diesel, and industrial oils.

Quality Control

Our Trimethylphenol is manufactured under a stringent quality management system. Every batch undergoes rigorous analytical testing, including chromatography and spectroscopy, to ensure it meets precise purity and compositional specifications. Certificates of Analysis (COA) documenting identity, assay, and impurity profiles are provided to guarantee consistency and compliance with your application requirements.

Storage

Preserve in a tightly closed container, protected from light. Store in a cool, dry, well-ventilated area at room temperature (15-25°C). This material is easily oxidized; for long-term storage or after opening, consider storing under an inert atmosphere (e.g., nitrogen) to maintain optimal quality. Keep away from strong oxidizing agents.
