Metabolite Identification
Common NameNaproxen
DescriptionNaproxen, also known as naprosyn or (S)-naproxen, belongs to the class of organic compounds known as naphthalenes. Naphthalenes are compounds containing a naphthalene moiety, which consists of two fused benzene rings. Naproxen is an extremely weak basic (essentially neutral) compound (based on its pKa).
