3,4-Dimethylphenol (CAS 95-65-8) is an organic compound with a hydroxyl-substituted aromatic ring, commonly used as a precursor in pharmaceuticals, agrochemicals, and specialty polymers for its reactive methyl groups. It is used chiefly as a starting material for phenolic resins and also serves as a corrosion inhibitor. It appears as a white to off-white crystalline solid with a characteristic phenolic odor. This chemical has a molecular formula of (CH3)2C6H3OH and a molecular weight of 122.16 g/mol. It must be stored between 2 to 8°C in a cool, dry place, away from incompatible substances, and handled with care due to its hazardous classification (Signal word: Danger). Molekula supplies 3,4-Dimethylphenol from research to bulk quantities with full documentation and ISO 9001:2015 traceability.
