Wurster salts are brightly colored salts, named after their discoverer Casimir Wurster (1856–1913). The representatives of this group of substances arise from the partial oxidation of N -alkylated p - phenylenediamines . The Wurster salts belong structurally to the paramagnetic radical cations , which was researched by Ernst Weitz (1883–1954) and Leonor Michaelis (1875–1949).
