Chemical Information
FooDB NameC.I. Food Black 2
DescriptionC.I. Food Black 2 belongs to the class of organic compounds known as 2-naphthalene sulfonates. These are organic aromatic compounds that contain a naphthalene moiety that carries a sulfonic acid group at the 2-position. Naphthalene is a bicyclic compound that is made up of two fused benzene ring. Based on a literature review very few articles have been published on C.I. Food Black 2.
