Phenoxypropanol

Updated: 2026-07-25

Overview

Phenoxypropanol is an organic compound with versatile applications across multiple industries. As a phenyl ether derivative of propylene glycol, it serves as a valuable intermediate in pharmaceutical synthesis and as a solvent in specialty formulations. The compound's chemical structure combines lipophilic and hydrophilic properties, making it particularly useful in applications requiring controlled solubility. Its stability under various conditions contributes to its widespread industrial adoption.

Physical and Chemical Properties

Phenoxypropanol presents as a colorless to slightly yellow viscous liquid with a characteristic mild aromatic odor. Its high boiling point (243-245°C) makes it suitable for high-temperature applications where lower volatility solvents would evaporate too quickly. The compound demonstrates good solubility in most organic solvents including alcohols, ethers, and ketones, while being only sparingly soluble in water. This amphiphilic nature allows it to function as a coupling agent in systems requiring both polar and non-polar components.

Main Applications

In the pharmaceutical industry, phenoxypropanol serves as a key building block for synthesizing various active pharmaceutical ingredients (APIs). Its chemical structure allows for straightforward derivatization to create more complex molecules. The fragrance industry utilizes phenoxypropanol as a fixative and solvent due to its mild odor profile and excellent solvent properties for aromatic compounds. Industrial applications include use in specialty inks, coatings, and adhesives where it functions as a high-boiling point solvent and viscosity modifier.

Safety and Storage

While not classified as extremely hazardous, phenoxypropanol requires careful handling to prevent exposure. The compound can cause irritation to eyes, skin, and respiratory system upon contact or inhalation. Proper storage involves keeping containers tightly sealed in a cool, dry area with adequate ventilation. Secondary containment is recommended to prevent environmental contamination in case of spills. Fire safety measures should include using alcohol-resistant foam for extinguishing, as water may be ineffective.

B2B Procurement Guide

When sourcing phenoxypropanol, buyers should specify required purity levels (typically 98% or higher for pharmaceutical applications) and request certificates of analysis. Technical grade may be acceptable for industrial uses. Consider transportation costs and logistics, as the compound may be classified differently across regions. Building relationships with specialized chemical distributors can provide access to technical support and more favorable pricing structures, especially for regular procurement needs.
