Description

2-Methyl-5-(1,1,3,3-Tetramethylbutyl)Hydroquinone is a specialized alkylated hydroquinone derivative that serves as a highly effective polymerization inhibitor and antioxidant. Its primary commercial value lies in its ability to stabilize monomers and other sensitive chemicals against premature polymerization during storage, transport, and processing. This compound is essential for manufacturers in the polymer, petrochemical, and specialty chemical industries who require reliable process control and product shelf-life extension.

Application

• Polymerization Inhibitor for vinyl monomers such as styrene, acrylates, and butadiene during production and storage.
• Antioxidant Stabilizer in fuels, lubricants, and petrochemical feedstocks to prevent gum formation and oxidative degradation.
• Intermediate in the synthesis of more complex antioxidants and light stabilizers for plastics and coatings.
• UV Stabilizer Precursor used in the manufacturing of additives for polymers exposed to sunlight.
• Chemical Synthesis as a building block for specialty chemicals and pharmaceutical intermediates.
• Photographic Chemical in specific developer formulations and as an anti-fogging agent.

Quality Control

Our production of 2-Methyl-5-(1,1,3,3-Tetramethylbutyl)Hydroquinone adheres to stringent quality management protocols. Every batch undergoes comprehensive analytical testing to ensure identity, purity, and performance specifications are met. A detailed Certificate of Analysis (COA) is provided with each shipment, documenting key parameters such as assay, melting point, and impurity profiles. We support customer audits and can provide material to meet specific regulatory or internal quality standards upon request.

Storage

Preserve in a tightly closed container, protected from light. Store in a cool, dry, and well-ventilated area at room temperature (15-25°C). This material is easily oxidized; for long-term storage, maintaining an inert atmosphere (e.g., under nitrogen) is recommended to preserve efficacy. Keep away from strong oxidizing agents and incompatible materials.
