To effectively utilize 4-Methoxyphenol (MEHQ) in industrial processes, a thorough understanding of its chemical properties and safe handling practices is essential. MEHQ, or Mequinol, with the CAS number 150-76-5, is a white crystalline solid with a molecular formula of C7H8O2. Its physical and chemical characteristics dictate its performance as a polymerization inhibitor and chemical intermediate.

MEHQ exhibits moderate solubility in water and is soluble in many organic solvents like alcohol, ether, and benzene. Its melting point is typically between 54.0-56.5°C, and its boiling point is around 243°C. These properties are important for process design and formulation. As a phenolic compound, it can undergo various chemical reactions, including etherification and esterification, which are leveraged in its role as a chemical intermediate. The purity standard, often specified as ≥99.5%, is crucial for its intended applications, especially in pharmaceuticals and high-grade cosmetics.

Safety and handling are paramount when working with MEHQ. It can cause skin and eye irritation upon direct contact, and inhalation of its dust or vapors should be avoided. Standard industrial hygiene practices, including the use of personal protective equipment (PPE) such as gloves, safety glasses, and respiratory protection in dusty environments, are recommended. Storage should be in a cool, dry, well-ventilated area, away from incompatible materials like strong oxidizing agents and halogens. Proper labeling and containment are vital to prevent accidental exposure or reactions.

When sourcing this chemical, looking for 4-methoxyphenol suppliers price and availability from reputable sources is key. Companies often provide detailed Safety Data Sheets (SDS) and Technical Data Sheets (TDS) that offer comprehensive information on properties, hazards, and handling recommendations. Adhering to these guidelines ensures that the industrial potential of MEHQ is realized safely and efficiently, minimizing risks and maximizing the benefits of this versatile chemical compound.
