2,6-Di-tert-butyl-4-(dimethylaminomethyl)phenol

2,6-Di-tert-butyl-4-(dimethylaminomethyl)phenol (CAS 88-27-7), sold commercially as Ionol 103, is a hindered phenolic antioxidant with an integrated amine functionality. It protects hydrocarbon-based materials from oxidative degradation during processing and long-term service. In lubricant formulations, it functions as a multifunctional additive that delivers both antioxidant protection and mild metal-passivating activity. This extends oil service life in industrial and automotive systems.

Rubber compounders incorporate it to inhibit thermal and oxidative aging in finished goods such as seals, hoses, and tire components. This ensures the durability and performance of rubber products over time. Polymer processors use it to stabilize polyolefins and other plastics against degradation during high-temperature extrusion and molding. It prevents the loss of mechanical properties during the manufacturing process.

In oil and gas applications, it is added to fuel streams and process fluids to prevent oxidative deterioration during storage and transmission. This maintains the quality and stability of the chemical streams. The product is typically supplied as a liquid or low-melting solid. It is available in technical grade, the standard specification for industrial antioxidant applications across lubricants, rubber, and polymer sectors.

Bulk supply is common in drums or IBC containers, with packaging options aligned to industrial procurement volumes. This ensures efficient handling and integration into large-scale chemical manufacturing workflows.
