Flmodafinil (CRL-40,940)

CRL-40,940 (Flmodafinil, Lauflumide) is a derivative of Modafinil, a medication used for narcoleptics by increasing attention and reducing sleep cravings. CRL-40,940 is classified as a psychotronic and eugeroic and has demonstrated similar but somewhat more powerful effects than Modafinil in animal models.

Chemically, CRL-40,940 (Lauflumide) is the bis(p-fluoro) derivative of Modafinil and is sometimes referred to as bisfluoromodafinil or Flmodafinil.

Modafinil, Adrafinil, Flmodafinil (CRL-40,940), and CRL-40,941 are part of the same family of eugeroics that were initially discovered in the late 1970’s by Dr. Michel Jouvet’s French ‘Laboratorie Lafon’. At Lafon, the research team made several observations of the newly synthesized group of drugs.
