8-Anilino-1-naphthalene sulfonate belongs to the class of organic compounds known as 1-naphthalene sulfonic acids and derivatives. These are organic aromatic compounds that contain a naphthalene moiety that carries a sulfonic acid group (or a derivative thereof) at the 1-position. Naphthalene is a bicyclic compound that is made up of two fused benzene ring.Naphthalene has been detected in indoor air. It is a product of combustion when organic materials are burned. Tobacco smoking, cooking, and moth repellents may all be sources of naphthalene indoors. 1; Clothing stored with naphthalene mothballs may adsorb the naphthalene.
