Usage
2,6-Dimethylphenol is widely used in:

• Organic synthesis as a key intermediate

• Production of polyphenylene ether (PPE) polymers, which are engineering plastics with high heat resistance and dimensional stability

• Manufacture of antioxidants for polymers

• Raw material for pharmaceuticals, disinfectants, solvents, plasticizers, and wetting agents

Packaging and Transportation

• Typically supplied in 200 kg drums or smaller quantities such as 25 g, 500 g, 1 kg glass bottles depending on supplier

• Classified as UN 2261, Hazard Class 6.1 (toxic substances), Packing Group II

• Transport requires adherence to regulations for toxic and corrosive materials, including proper labeling and containment to prevent environmental release

Storage

• Store in a cool, dry, well-ventilated area away from incompatible materials such as alkalis, acid chlorides, acid anhydrides, oxidants, brass, copper, and copper alloys

• Recommended storage temperature varies by supplier: refrigerated at 0-10 °C or below 30 °C

• Keep containers tightly closed and under inert gas if possible to avoid air sensitivity

• Avoid exposure to moisture and direct sunlight
