People who wore socks, gloves, and shirts colored with aniline, or shoes that had been shined with an aniline-based polish, often suffered inflammatory skin reactions or headaches and dizziness… because the dye was poisoning their blood.
Aniline is a toxic organic compound with the formula C6H5NH2. Consisting of a phenyl group attached to an amino group, aniline is the prototypical aromatic amine. Its main use is in the manufacture of precursors to polyurethane and other industrial chemicals. Like most volatile amines, it possesses the odor of rotten fish. It ignites readily, burning with a smoky flame characteristic of aromatic compounds.
