1,2-Diphenoxyethane (DPE) is a high-purity, aromatic ether valued for its excellent thermal and chemical stability. Its high boiling point , low volatility, and strong solvency make it ideal for specialized roles in thermal paper formulations, precision solvent systems, and fine chemical synthesis. In thermal paper coatings, DPE functions as a sensitizer component to enhance image density and print response when used alongside developers and leuco dyes.
1, 2-Diphenoxyethane (DPE) offers a unique combination of thermal stability, low volatility, and selective solubility, making it an ideal component in high-performance applications such as thermal paper coatings, Polymer Additive and precision chemical formulations.
DPE retains structural integrity under elevated temperatures and harsh chemical conditions, with a melting point of 94–96°C and a boiling point of ~341°C at atmospheric pressure (approx. 185°C under reduced pressure), ensuring consistent performance in demanding environments.
With a vapor pressure of 0 Pa at 25°C, DPE minimizes evaporation loss, improving safety and storage stability in both laboratory and industrial settings.
Slightly soluble in water (~22 mg/L at 25°C) yet highly compatible with a broad range of organic solvents, DPE enables flexible integration into solvent systems, resins, coatings, and advanced chemical processes.

1,2-Diphenoxyethane (DPE) is generally stable and safe when handled under recommended conditions. However, to ensure safe usage and maintain a safe working environment, please adhere to the following standard chemical handling precautions:
At Heni Chemicals, safety and product quality are our top priorities. Each shipment of 1,2-Diphenoxyethane is accompanied by a comprehensive Safety Data Sheet (SDS) and a Certificate of Analysis (COA) to ensure compliance with regulatory standards and to support safe handling procedures. Always consult these documents before use and implement all recommended safety practices.
With decades of experience in chemical sourcing and formulation, Heni Chemicals has become a trusted name across global markets. Here's what sets our DPE apart:
Our production and QA teams follow internationally accepted standards to ensure that every shipment meets regulatory and performance benchmarks. Whether you need small research quantities or large commercial volumes, we can scale with your needs.
DPE is used in thermal paper, electronics, industrial lubricants, coatings, and specialty chemical formulations due to its excellent stability and solvent compatibility.
DPE typically has a shelf life of up to 36 months when stored in original, sealed containers at room temperature and away from moisture or direct sunlight.
Yes. Heni Chemicals offers custom purity levels and blended grades based on your application needs — including thermal coatings, solvent systems, and lab-scale testing.
DPE is not classified as hazardous under GHS, but standard safety precautions should be followed. Use gloves, goggles, and ensure good ventilation. Always refer to the Safety Data Sheet (SDS).
No. DPE is hydrophobic and not soluble in water. It is best suited for solvent-based, non-aqueous, or hydrocarbon-compatible systems.
