These compounds, along with 1,4‐diaminophenylene and benzidine were examined in the Salmonella microsome assay with strains TA98 and TA100. The results of this study indicate that the mutagenicity of these diamines was the greatest for 4,4′‐diamino‐p‐terphenyl, followed by diaminophenylene and benzidine, with 4,4′‐diamino‐p‐quaterphenyl showing no mutagenicity.}, number={1}, journal={COLORATION TECHNOLOGY}, author={Wang, Jinlong and Freeman, Harold S. and D Claxton, Larry}, year={2007}, pages={34–38} }

The formation of the target dyes was confirmed by electrospray mass spectrometry and their mutagenicity was examined in the Salmonella microsome assay using TA98 and TA100. While most of these dyes were clearly non‐mutagenic, results from the Prival modification of the standard assay showed that Congo Red and its homologue derived from 4,4′‐diamino‐p‐terphenyl were clearly mutagenic.}, number={1}, journal={COLORATION TECHNOLOGY}, author={Wang, Jinlong and Freeman, Harold S. and D Claxton, Larry}, year={2007}, pages={39–45} }
