3,5-dimethylphenol

3,5-dimethylphenol is an organic compound with the molecular formula C8H10O and CAS number 108-68-9. It belongs to the phenol family and features two methyl groups attached to the benzene ring at positions 3 and 5. With a molecular weight of 122.16 g/mol, this aromatic compound is classified as a hazardous substance with acute toxicity and skin corrosion properties, requiring careful handling in industrial applications.

3,5-dimethylphenol is typically a white to pale yellow crystalline solid at room temperature with a characteristic phenolic odor. As a phenolic compound, it exhibits moderate solubility in water and good solubility in organic solvents such as alcohols and ethers. The compound has a melting point around 63-65°C and demonstrates typical aromatic stability while maintaining the reactive hydroxyl group characteristic of phenols.

3,5-dimethylphenol is primarily used as an intermediate in the synthesis of pharmaceuticals, agrochemicals, and specialty chemicals. It serves as a building block for manufacturing antioxidants, preservatives, and various organic compounds. The compound is also utilized in the production of resins, polymers, and as a chemical intermediate in the synthesis of more complex aromatic compounds for industrial applications.

3,5-dimethylphenol requires strict safety measures due to its Acute Tox. 3 and Skin Corr. 1B classifications. Essential protective equipment includes chemical-resistant gloves, safety goggles, and protective clothing to prevent skin contact. Work should be conducted in well-ventilated areas or under fume extraction systems. The GHS06 and GHS05 pictograms indicate both acute toxicity and corrosive hazards, requiring immediate medical attention if exposure occurs.

3,5-dimethylphenol should be stored in tightly sealed containers in a cool, dry, well-ventilated area away from heat sources and direct sunlight. Storage areas must be equipped with appropriate containment measures and maintained at stable temperatures. The compound should be kept away from incompatible materials such as strong oxidizing agents and bases. Regular container inspection is essential to prevent leakage and ensure integrity.

Immediate action is required due to the compound's corrosive properties. For skin contact, remove contaminated clothing and flush affected areas with plenty of water for at least 15 minutes, then seek medical attention immediately. In case of eye contact, rinse thoroughly with water for at least 15 minutes and obtain emergency medical care. If inhaled, move the person to fresh air and seek medical attention if breathing difficulties occur.

3,5-dimethylphenol disposal must comply with local and national hazardous waste regulations due to its toxic and corrosive properties. The compound should never be poured down drains or disposed of with regular waste. Professional hazardous waste disposal services should handle collection and treatment, typically through high-temperature incineration at authorized facilities. Proper documentation and waste classification codes must accompany all disposal activities.

3,5-dimethylphenol is classified as ADR Class 6.1 (toxic substances), Packaging Group II, requiring specific transport regulations compliance. Packages must be properly labeled with appropriate hazard markings and UN identification numbers. Transport vehicles need proper documentation including safety data sheets and emergency response information. Only certified carriers experienced in hazardous materials transport should handle shipments, ensuring proper containment and emergency preparedness throughout transit.

3,5-dimethylphenol is subject to REACH regulation for registration and authorization within the EU market. The compound falls under CLP regulation requiring proper classification, labeling, and packaging with GHS06 and GHS05 pictograms. While not currently listed as an SVHC substance, it remains subject to standard chemical safety assessments and may face additional restrictions depending on specific applications and exposure scenarios in different EU member states.
