25I-NBOMe has efficacy at the [[serotonin#The 5-HT system|5-HT<sub>2A</sub> receptor]] where it acts as an unusually potent and selective [[Agonist#Agonists|partial agonist]].<ref name="pmid21174090">Ettrup, A.

This compound is pharmacologically unique when compared to other psychedelics through its action on [[serotonin]] receptors. It is one of the only [[Agonist#Agonists|full agonists]] for the human [[Serotonin#The 5-HT system|5-HT<sub>2A</sub> receptor]] receptor in existence.<ref name="pmid21174090" /> In comparison, classical psychedelics such as [[LSD]], [[DMT]] and [[psilocin]] can only be considered [[Agonist#Agonists|partial agonists]].  
Among psychedelics, this compound is considered to be pharmacologically unique in terms of the high potency, affinity, and selectivity with which it binds to the 5HT-2a receptor.<ref name="pmid21174090" /> Contrary to popular belief, it is not a "full agonist", although questions have been raised about how the effects it produces differ from other 5HT-2a partial agonists, which include the range of traditional psychedelics.
