Description

2,6-Di-tert-Butyl-4-(2-(3-Pyridinyl)Ethenyl)Phenol is a specialized phenolic antioxidant compound featuring a pyridinyl ethenyl substituent, which imparts unique chemical functionality. This compound matters for its dual role as a high-performance antioxidant and a versatile chemical intermediate, offering enhanced stability to materials susceptible to oxidative degradation. It is primarily needed by R&D chemists and formulators in the polymer, pharmaceutical, and specialty chemical industries seeking to develop advanced stabilization systems or novel molecular architectures.

Application

• Polymer Stabilizer: Acts as a highly effective antioxidant and light stabilizer in polyolefins (e.g., polyethylene, polypropylene), engineering plastics, and synthetic rubbers to extend product lifespan.
• Pharmaceutical Intermediate: Serves as a key building block in the synthesis of novel drug candidates, particularly those targeting neurological or inflammatory pathways, due to its phenolic and heterocyclic structure.
• Lubricant & Fuel Additive: Used as an antioxidant additive in high-performance lubricating oils, greases, and industrial fuels to prevent oxidation and sludge formation.
• Research & Development: Employed in academic and industrial research for studying antioxidant mechanisms, developing new material stabilizers, or creating functionalized polymers.
• Specialty Chemical Synthesis: Utilized as a precursor or intermediate for synthesizing more complex antioxidants, UV absorbers, or ligands for catalytic systems.

Quality Control

Our production of 2,6-Di-tert-Butyl-4-(2-(3-Pyridinyl)Ethenyl)Phenol adheres to a stringent quality management system. Every batch undergoes rigorous analytical testing to ensure identity, purity, and consistency meet the high standards required for industrial and research applications. A comprehensive Certificate of Analysis (COA) detailing purity (typically >97% by HPLC), physical characteristics, and impurity profiles is provided with each shipment and is available upon request.

Storage

Preserve in a tightly closed container, protected from light. Store in a cool, dry, and well-ventilated area at a controlled room temperature (15-25°C). Keep away from heat, sparks, and open flame. Due to its light-sensitive nature, the container should be opaque or stored in dark conditions to maintain product integrity.
