Abstract 2,4-Diaminotoluene, an aromatic amine hepatocarcinogen in rats and mice, reacts extensively with formaldehyde produced by the oxidation of methanol to form a single reaction product. Using 1H and 13C NMR and high-resolution mass spectroscopy, this product was shown to be bis(2,4-diamino-5-tolyl)methane. This reaction product is shown to occur under conditions whereby methanol is metabolized to formaldehyde by rat hepatic postmitochondrial supernatant. These results demonstrate a novel reaction of aromatic amines and formaldehyde in biological samples and indicate that methanol as a solvent may become activated in vitro and produce complex interactions with solutes.
