| Uses | DTPD-Q is the transformation products (TATPs) of tire additives N,N′-diphenyl-p-phenylenediamine (DTPD). DTPD-Q accumulates and rises the ecological risk in the environment[1]. | | References | [1] Wei LN, et al., First Evidence of the Bioaccumulation and Trophic Transfer of Tire Additives and Their Transformation Products in an Estuarine Food Web.
