The melting point of E-stilbene ranges from 122 to 125 °C (252 to 257 °F; 395 to 398 K).
E-stilbene, also known as trans-stilbene, is an organic compound and a hydrocarbon, specifically a diarylethene. It exists as a white crystalline solid at room temperature and is known for its trans configuration around its central double bond, which gives it distinct physical properties compared to its cis isomer.

Understanding Melting Point
The melting point is a crucial physical property of a substance, indicating the temperature at which it changes from a solid to a liquid state. For crystalline solids like E-stilbene, the melting point is often a sharp and characteristic temperature. The small range provided (e.g., 122 to 125 °C) accounts for minor impurities or experimental variations.
Applications and Importance
E-stilbene and its derivatives are of interest in various fields due to their photochemical properties and their ability to undergo trans-cis isomerization. They are used in:
- Organic synthesis: As intermediates in the production of more complex molecules.
- Material science: For developing light-emitting materials and molecular switches.
