For chemists, formulators, and procurement specialists in the B2B chemical sector, a thorough understanding of a compound's properties is vital for successful application and sourcing. Guaiacol (CAS 90-05-1), also known as 2-methoxyphenol, is a prime example of a versatile chemical intermediate with significant industrial importance. This article delves into the core chemical properties of Guaiacol and elucidates its critical roles across various industries, emphasizing the benefits of sourcing from reputable manufacturers.

Guaiacol is an aromatic organic compound with the molecular formula C7H8O2. Its structure features a hydroxyl group and a methoxy group attached to a benzene ring, which dictates its reactivity and physical characteristics. Typically appearing as colorless to light yellow crystals or an oily liquid, Guaiacol possesses a characteristic smoky and phenolic odor. Its melting point is around 27-32 °C, meaning it can exist as a solid or liquid depending on ambient temperature. This dual nature requires careful handling and storage, especially for bulk purchases.

The chemical reactivity of Guaiacol makes it a valuable intermediate. The phenolic hydroxyl group allows for reactions such as etherification and esterification, while the aromatic ring can undergo electrophilic substitution. Its primary applications stem from these properties:

1. Flavor and Fragrance Industry: Guaiacol is a fundamental building block for synthesizing key aroma chemicals like vanillin and artificial musk. Its inherent smoky and phenolic notes are also directly utilized in creating specific flavor profiles for food products and complex scent compositions for perfumes.

2. Pharmaceuticals: It serves as a precursor in the synthesis of pharmaceutical agents, most notably calcium guaiacol sulfonate, an expectorant used in cough remedies. Sourcing high-purity Guaiacol is essential for pharmaceutical intermediates to meet regulatory standards.

3. Industrial Applications: Beyond these, Guaiacol can be used in analytical chemistry as a reagent, for instance, in the detection of copper or nitrites.
