Understanding the fundamental chemical properties of industrial compounds is crucial for their effective application and procurement. 4-Methoxyphenol (MEHQ), identified by CAS number 150-76-5, is a versatile organic compound that finds widespread use across various sectors due to its unique characteristics. For purchasing managers and chemical engineers, a comprehensive understanding of MEHQ's properties and applications is key to leveraging its full potential.

MEHQ is characterized as a white to off-white crystalline solid with a mild phenolic odor. Its molecular formula is C7H8O2, and it possesses a relatively high boiling point (around 243°C) and a melting point of approximately 54-56°C. A significant chemical property is its solubility in common organic solvents like alcohol and ether, though it has limited solubility in water. This solubility profile makes it adaptable to various formulation types.

Industrially, MEHQ's primary function is as a polymerization inhibitor and a UV stabilizer. It effectively prevents the premature polymerization of monomers like acrylates, methacrylates, and styrene, thereby extending their shelf life and ensuring safe handling. This property is invaluable in the manufacturing of polymers, resins, paints, inks, and adhesives. Additionally, its UV-absorbing capabilities make it useful in protecting materials from photodegradation.

MEHQ also serves as a crucial chemical intermediate. It is utilized in the synthesis of antioxidants, pharmaceuticals, and agrochemicals. For instance, it is a precursor in the production of Butylated Hydroxyanisole (BHA), a common antioxidant in food and cosmetics. Its role as an intermediate means that companies manufacturing specialty chemicals can rely on MEHQ as a foundational component for their own product lines.

When sourcing MEHQ, purchasing professionals should focus on purity and reliability from manufacturers. High-quality MEHQ, supplied by established chemical producers, ensures consistent performance in critical applications. Investigating price points from various suppliers and understanding the product specifications, such as purity levels and physical form, will facilitate informed buying decisions. By understanding these properties, industries can effectively utilize MEHQ to enhance product stability, facilitate synthesis, and drive innovation.
