6PPD - Wikipedia
6PPD. Except where otherwise noted, data are given for materials in their standard state (at 25 °C [77 °F], 100 kPa). 6PPD is an organic chemical widely used as stabilising additive (or antidegradant) in rubbers, such as NR, SBR and BR; all of which are common in vehicle tires. [1] Although it is an effective antioxidant it is primarily used ...

Consistent with prior findings, 6PPDQ (C 18 H 22 N 2 O 2) was one of the major TPs in 6PPD ozonation (∼1 to 19% yield). Notably, 6PPDQ was not observed during ozonation of 6QDI ( N -(1,3-dimethylbutyl)- N ′-phenyl- p -quinonediimine), indicating that 6PPDQ formation does not proceed through 6QDI or associated 6QDI TPs.

6PPD-Quinone: Revised Toxicity Assessment and Quantification ...
Stormwater exposure can cause acute mortality of coho salmon (Oncorhynchus kisutch), and 6PPD-quinone (6PPD-Q) was identified as the primary causal toxicant. Commercial standards of 6PPD-Q recently became available; their analysis highlighted a systematic high bias in prior reporting concerning 6PPD-Q. A 6PPD-Q commercial standard was used to re-confirm toxicity estimates in juvenile coho ...
