Guaiacol, a significant organic compound with the chemical formula C7H8O2 and CAS number 90-05-1, is a versatile chemical that finds extensive application across multiple industries. Its unique phenolic structure, characterized by a hydroxyl and a methoxy group attached to a benzene ring, grants it a distinct smoky, woody aroma and a range of useful chemical properties. This makes it a sought-after ingredient and intermediate in sectors ranging from food flavoring to pharmaceuticals and beyond.

The physical properties of Guaiacol are noteworthy. It typically appears as a colorless to yellowish, oily liquid, with a melting point of -20°C, indicating its liquid state at standard room temperatures. This physical form facilitates its handling and incorporation into various liquid formulations. Chemically, Guaiacol is moderately soluble in water and highly soluble in organic solvents, which enhances its utility in extraction and synthesis processes.

The applications of Guaiacol are broad and impactful. In the flavor and fragrance industry, it is a key component for creating smoke flavors, enhancing coffee and whiskey notes, and crucially, serving as a precursor for the synthesis of vanillin, a globally consumed flavoring agent. Its pharmaceutical significance lies in its expectorant properties, aiding in mucus clearance, and its antiseptic capabilities, which are valuable in various medicinal preparations. Furthermore, Guaiacol acts as a valuable intermediate in the synthesis of dyes and serves as a reliable analytical reagent in chemical laboratories.

Market trends indicate a steady demand for Guaiacol, driven by the consistent growth in the food and beverage, pharmaceutical, and personal care sectors. The increasing consumer preference for natural and nature-identical flavors also bolsters the demand for Guaiacol, particularly for vanillin production. As industries continue to innovate, exploring new applications for this phenolic compound remains an ongoing area of interest.

For businesses looking to procure Guaiacol, understanding the sourcing options is vital. Manufacturers and suppliers offer various grades, with high purity (e.g., 99%) being standard for many industrial applications. Purchasing options often include sample orders, allowing for testing and validation before bulk acquisition. Access to technical data sheets and certificates of analysis is crucial for ensuring quality and compliance, especially for pharmaceutical and food-grade applications. The consistent demand and diverse utility of Guaiacol suggest a stable and robust market presence for this essential chemical compound.
