Modafinil acid (code name CRL-40467), also known as modafinilic acid or modafinil carboxylate, is the major metabolite of modafinil, and one of the two major metabolites of modafinil – the other being modafinil sulfone. Modafinil acid is also a metabolite of the modafinil prodrug, adrafinil, and the (R)-(–)-enantiomer is a metabolite of armodafinil, the (R)-(–)-enantiomer of modafinil. Modafinil acid seems to be inactive, and similarly to modafinil sulfone, does not appear to contribute to the wakefulness-promoting/psychostimulant effects of modafinil.
