Product Description:

4-Methylguaiacol, also known as creosol, is an organic compound with the molecular formula C8H10O2. It is a derivative of guaiacol, featuring a methyl group at the para position relative to the methoxy group. This compound is a colorless to pale yellow liquid with a characteristic smoky, spicy, and medicinal odor. Its primary and most significant application is as a flavor and fragrance ingredient. It is widely used in the food industry to impart smoky, spicy, or medicinal notes to various products, including meat flavorings, sauces, and certain alcoholic beverages. In the fragrance industry, it serves as a key component in creating woody, smoky, and leathery accords for perfumes, cosmetics, and personal care products. It is also a constituent of natural products like wood smoke and certain essential oils. While it has some historical use as a disinfectant and expectorant, these applications are now minor. 4-Methylguaiacol is generally recognized as safe (GRAS) for use as a flavoring agent by regulatory bodies when used within specified limits. It is primarily valued for its organoleptic properties in flavor and fragrance formulations.
