Propyl phenyl ether

Updated: 2026-07-23

Overview

Propyl phenyl ether, also known as phenoxypropane, is an organic compound belonging to the ether class. It is characterized by its aromatic odor and is commonly used in industrial applications. The compound is synthesized through the Williamson ether synthesis, reacting phenol with propyl halides. Propyl phenyl ether is valued for its stability and solubility in various organic solvents. It is often utilized in the production of fragrances, pharmaceuticals, and as a reaction medium in organic chemistry. Its relatively low toxicity makes it suitable for controlled industrial use.

Propyl phenyl ether is a colorless to pale yellow liquid with a boiling point of 188-190°C and a melting point of -40°C. Its density is approximately 0.95 g/cm³, and it is sparingly soluble in water but miscible with most organic solvents like ethanol and ether. The compound exhibits low volatility and is stable under normal temperature and pressure conditions. Its chemical stability makes it a reliable solvent for reactions requiring inert conditions. However, it should be protected from strong oxidizing agents to prevent decomposition.

Main Applications

Propyl phenyl ether is primarily used as a solvent in the pharmaceutical and fragrance industries. Its ability to dissolve a wide range of organic compounds makes it ideal for formulations requiring consistent solubility. Additionally, it serves as an intermediate in the synthesis of more complex organic molecules, including agrochemicals and specialty chemicals. In fragrances, it contributes to the longevity and stability of scent formulations. Its applications extend to laboratory settings as a reaction medium for etherification and other organic reactions.

While propyl phenyl ether is not highly toxic, it should be handled with care to avoid skin contact, inhalation, or ingestion. Proper personal protective equipment (PPE) such as gloves and goggles is recommended during use. Storage should be in a cool, dry, well-ventilated area away from heat sources and open flames. Containers must be tightly sealed to prevent evaporation and contamination. In case of spills, absorb with inert material and dispose of according to local regulations.

B2B Procurement Guide

When procuring propyl phenyl ether, B2B buyers should prioritize suppliers who provide detailed material safety data sheets (MSDS) and certificates of analysis (CoA). These documents ensure product quality and compliance with safety standards. Bulk purchasing is advisable for cost efficiency, especially for industries requiring large volumes. Buyers should also verify the supplier's ability to meet regulatory requirements and provide consistent purity levels, typically 98% or higher for industrial applications.
