Description

Hexadecyl 3,5-di-tert-butyl-4-hydroxybenzoate is a sterically shielded phenolic antioxidant featuring a long alkyl chain that enhances compatibility with hydrophobic matrices. The para-hydroxyl group delivers radical-scavenging activity, while the ortho-di-tert-butyl substitution prevents oxidation and ensures prolonged stability in polymer and lubricant systems under thermal stress.

Application

Hexadecyl 3,5-di-tert-butyl-4-hydroxybenzoate functions as a stable, long-chain antioxidant ester, enabling effective radical scavenging in high-temperature and oxidative environments. Its tert-butyl substituents enhance steric protection of the phenolic OH group, while the hexadecyl chain provides excellent solubility in organic matrices and facilitates purification via crystallization or column chromatography. This compound serves as a robust additive in polymer stabilization and lubricant formulations.
