Metabolite Identification
Common Name2-Naphthaldehyde
Description2-Naphthaldehyde, also known as 2-formylnaphthalene, belongs to the class of organic compounds known as naphthalenes. Naphthalenes are compounds containing a naphthalene moiety, which consists of two fused benzene rings. 2-Naphthaldehyde is an extremely weak basic (essentially neutral) compound (based on its pKa). 2-Naphthaldehyde exists in all living organisms, ranging from bacteria to humans. These are compounds containing a naphthalene moiety, which consists of two fused benzene rings.
