3Propylphenol

3-Propylphenol, also known as m-propylphenol, is an aromatic phenolic compound with the molecular formula C9H12O. It is one of the three propyl-substituted isomers of phenol, with the propyl group attached at the meta position relative to the hydroxyl group on the benzene ring. At room temperature it is typically a colorless to pale yellow liquid, and it has a characteristic phenolic odor.

Industrially, 3-propylphenol can be produced by alkylation of phenol with propene or related hydrocarbon sources under acid catalysis, yielding the meta-substituted product. It may also be encountered as an intermediate in the synthesis of other organic compounds, including fragrance and flavor components, dyes, or agrochemical precursors, depending on the specific production stream and downstream chemistry.

In applications, 3-propylphenol is generally handled as a chemical intermediate or specialty aromatic compound. Its use is typically confined to manufacturing settings where it is converted into more complex molecules, rather than as a consumer chemical. The various propylphenol isomers (2- and 4-propylphenol areomers) reflect the flexibility of electrophilic substitution on the substituted benzene ring, but yields and purities depend on the chosen synthetic route.

Safety and handling are important, as phenols are corrosive and can be hazardous if skin or eye contact occurs, or if inhaled or ingested. Appropriate personal protective equipment, good ventilation, and adherence to hazardous-materials guidelines are recommended. Storage should be in a cool, well-ventilated area away from oxidizers and sources of ignition.
