Overview
2-methyl-5-(2,4,4-trimethylpentan-2-yl)benzene-1,4-diol (CAS 723-38-6) is an alkylated hydroquinone derivative with antioxidant properties and industrial stabilization capabilities. This specialized phenolic compound, with molecular formula C15H24O2 and molecular weight 236.35 g/mol, represents an important class of substituted benzene-1,4-diols used extensively in industrial applications. The molecule features a characteristic hydroquinone core structure enhanced with a methyl group and a branched trimethylpentan-2-yl substituent, which significantly influences its chemical behavior and commercial utility. The structural modifications provide enhanced lipophilicity compared to simple hydroquinone derivatives, making it particularly valuable in formulations requiring both antioxidant activity and compatibility with organic matrices. From a safety perspective, this substance requires careful handling protocols as it is classified under multiple hazard categories. The Eye Dam. 1 classification indicates severe eye damage potential, while the Skin Sens. 1 designation warns of possible allergic skin reactions. Environmental considerations include its Aquatic Chronic 2 classification, necessitating appropriate containment measures. The GHS05, GHS07, and GHS09 pictograms reflect these corrosive, health hazard, and environmental risks respectively, with transport classification under ADR Class 9 for miscellaneous dangerous substances. Industrial applications primarily center on its antioxidant properties, particularly in polymer stabilization, rubber processing, and specialty chemical formulations where oxidative degradation prevention is critical. Unlike simpler aromatic compounds such as 1-(4-aminophenyl)-N-methylmethanesulfonamide hydrochloride, this alkylated phenolic structure offers superior thermal stability and processing compatibility. The compound also finds application in fuel additives and lubricant formulations where long-term stability is paramount. OYSI maintains reliable supply chains for this technical-grade chemical compound, supporting diverse industrial requirements across European markets.
