Common NamePamoic acid
DescriptionPamoic acid, also known as pamoate, belongs to the class of organic compounds known as naphthalenecarboxylic acids. Naphthalenecarboxylic acids are compounds containing a naphthalene moiety, which bears a carboxylic acid group one or more positions. Naphthalene is a bicyclic compound that is made up of two fused benzene ring. Pamoic acid is considered to be a practically insoluble (in water) and relatively neutral molecule.
