Title: What does "valeryl" mean
Post by: Plasma on February 18, 2022, 10:25:17 AM

Good morning.  First time poster here :)

Can someone explain what valeryl means when naming compounds.

For example, there's fentanyl and valeryl fentanyl.  Valeryl fentanyl has an additional ethyl group attached but I'm struggling on why it's named the way it is.

Thanks

The root is from valeric acid (https://en.wikipedia.org/wiki/Valeric_acid), which has C5 carbon (pentanyl) chain. Most of the simple organic acids have common names (acetic, etc.) because they were identified before modern standardized naming. Those common names still find... well, common use. Nobody calls acetic acid "ethanoic acid".
