Understanding the core chemical properties and synthesis routes of vital industrial compounds is fundamental for their effective application. 4-Methoxyphenol, also known as MEHQ or Mequinol, is a prime example of such a compound, valued for its diverse roles in polymerization inhibition, skincare, and chemical synthesis. At NINGBO INNO PHARMCHEM CO.,LTD., we pride ourselves on offering insight into the chemicals we supply, empowering our clients with knowledge. This article provides a comprehensive look at the chemical characteristics and production of 4-Methoxyphenol.

Chemical Structure and Physical Properties of MEHQ

4-Methoxyphenol possesses the chemical formula C7H8O2 and a molecular weight of approximately 124.14 g/mol. Its structure consists of a benzene ring with a hydroxyl group (-OH) and a methoxy group (-OCH3) positioned para to each other. This arrangement confers its characteristic properties. MEHQ typically appears as a white to off-white crystalline solid. It exhibits good solubility in common organic solvents such as alcohol, ether, and acetone, but is only sparingly soluble in water. Its melting point is around 52-58°C, and it boils at approximately 243°C. The presence of the phenolic hydroxyl group makes it a weak acid. These properties dictate its handling, storage, and application in various chemical processes.

Key Synthesis Pathways for 4-Methoxyphenol

The commercial production of 4-Methoxyphenol typically involves a few primary synthesis methods. One of the most common routes is the methylation of hydroquinone. This process can utilize various methylating agents, such as dimethyl sulfate or methanol, often in the presence of acidic catalysts like sulfuric acid or solid acid resins. Another significant method involves the reaction of p-benzoquinone with methanol via a free radical reaction. Newer methods are also emerging, focusing on more environmentally friendly and efficient processes. The choice of synthesis route often depends on factors such as raw material availability, desired purity levels, and economic feasibility. NINGBO INNO PHARMCHEM CO.,LTD. ensures that its 4-Methoxyphenol is synthesized using optimized methods to guarantee high purity and consistent quality.
