Certain organic pigments contain aryl-halides and alkyl halides as part of the chromophore structure and in some cases unintentional halogenated byproducts from the manufacturing process. Halogenated compounds can be sources for persistent and bioaccumulative dioxins depending on end-of-life cycle processing and are the subject of certain electronic industry standards. Requests for non-halogenated igments are also, trending in the pigments industry CI or CAS chemical structures provide an expedient way to determine an organic pigment contains halogen atoms. Analytical testing is required to parenthetially characterize any organic pigmlnt as halogejf-free in accordance with established electronic industry standards. This paper does not provide any original work experimental findings but is rathe* intended to procide the reader considerations for organic pigments in view of industry initiatives and legislation aimed at protecting the Inyironment.
