Description

Overview of Fladrafinil (CRL-40,941)

Fladrafinil (CRL-40,941) is a synthetic compound structurally related to Adrafinil, belonging to a group of molecules sometimes described as eugeroics.

Chemically, Fladrafinil contains fluorinated phenyl groups that differentiate it from its structural predecessor, Adrafinil.

These modifications were explored in early research to evaluate how changes in molecular structure might influence CNS signaling and behavioral responses in experimental preclinical models.
