CAS: 93-51-6
Creosol (CAS: 93-51-6), chemically known as 2-methoxy-4-methylphenol, is a natural organic compound found as a major component of wood tar creosote and coal tar creosote. It is a colorless to yellowish liquid with a characteristic smoky, phenolic odor. It belongs to the class of guaiacols and methylphenols, possessing both a methoxy and a methyl group on a phenol ring.
Creosol is primarily used as a flavoring agent in the food and beverage industry to impart smoky and spicy notes. It also serves as a fragrance ingredient in perfumery and cosmetics. Additionally, it acts as a chemical intermediate in the synthesis of various organic compounds. Historically, it was associated with medicinal applications due to its presence in creosote, such as an antiseptic and expectorant, though its direct use in modern medicine is limited.
Its applications include flavoring in processed meats, BBQ sauces, snacks, and certain beverages to provide a smoky profile. In the fragrance industry, it's used in soaps, detergents, perfumes, and other personal care products for its woody, phenolic aroma. In the chemical industry, it serves as a building block for the synthesis of pharmaceuticals, agrochemicals, and other specialty chemicals.
Creosol is classified as harmful if swallowed, in contact with skin, or inhaled (H302, H312, H332). It causes skin irritation (H315) and serious eye irritation (H319). It is also a flammable liquid and vapor (H226). Appropriate personal protective equipment (PPE) such as gloves, eye protection, and protective clothing should be worn during handling. It should be used in well-ventilated areas. Environmental hazards indicate it is harmful to aquatic life with long lasting effects (H411).
