4-tert-Butyl-2,6-diformylphenol

Updated: 2026-07-15

Overview

4-tert-Butyl-2,6-diformylphenol is a specialized phenolic compound featuring two formyl groups and a tert-butyl substituent on the aromatic ring. Its molecular structure combines the antioxidant properties of phenols with the reactivity of aldehyde functionalities, making it valuable in polymer chemistry and specialty synthesis. Industrially, this compound serves as a building block for advanced antioxidants and stabilizers, particularly in high-performance plastics and elastomers. Its bifunctional nature allows for further chemical modifications, enabling tailored applications in material science and fine chemicals.

Physical and Chemical Properties

The compound exhibits typical phenolic characteristics with enhanced stability due to the tert-butyl group. Its crystalline form and moderate melting point facilitate handling in industrial processes. The formyl groups are reactive sites that participate in condensation and addition reactions, useful for creating larger molecular architectures. Solubility in polar organic solvents makes it suitable for solution-phase reactions, while its limited water solubility requires careful consideration in aqueous applications. Thermal gravimetric analysis typically shows decomposition above 200°C, indicating stability under common processing conditions.

Main Applications

Primary use cases include polymer stabilization, where it acts as a radical scavenger to prevent oxidative degradation in plastics like polyolefins and PVC. The formyl groups enable covalent bonding to polymer matrices, creating permanent stabilization effects rather than migratory additives. In fine chemistry, it serves as a precursor for Schiff base ligands in catalysis and as a scaffold for pharmaceutical intermediates. Some formulations incorporate it as a synergist with primary antioxidants to enhance performance in lubricants and coatings.

Safety and Storage

As with many phenolic compounds, appropriate handling precautions are essential. Dust control measures should be implemented during transfer operations, and chemical-resistant gloves (nitrile or neoprene) are recommended to prevent skin irritation. Storage should maintain product integrity - original containers with tight lids in secondary containment are ideal. Shelf life typically exceeds two years when protected from humidity and extreme temperatures. Spills should be contained with inert absorbents and disposed as hazardous waste according to local regulations.

B2B Procurement Guide

Industrial buyers should prioritize suppliers who provide comprehensive technical data sheets with batch-specific analysis. Key specifications to verify include HPLC purity (>98%), residual solvent content, and particle size distribution for consistent processing. Bulk purchases (drum quantities or larger) often attract volume discounts, but sample testing is advisable for new suppliers. Just-in-time inventory strategies help minimize storage duration. Consider regional suppliers to reduce logistics costs for this moderate-value chemical.
