| Analysis Note: | These products are for test and assay use only. They are not meant for administration to humans or animals and cannot be used to diagnose, treat, or cure diseases of any kind. |
| Application: | Aniline USP reference standard, intended for use in specified quality tests and assays as specified in the USP compendia. |
| Biochem/physiol Actions: | The acute toxicity of aniline involves its activation in vivo to 4-hydroxyaniline and the formation of adducts with hemoglobin. In erythrocytes, this is associated with the release of iron and the accumulation of methemoglobin and the development of hemolytic anemia and inflammation of the spleen. Tumor formation is often observed in the spleen on prolonged administration. |
