auramine O

Description

A bright yellow crystalline solid that is used as a dye for Paper and Leather. Auramine is a ketone imine compound that was first sold under the brand name Auramine O. It has been used in the preparation of ball point pens, carbon paper, printing inks, and typewriter ribbons. It is also used as a Fungicide, Disinfectant, and Fluorochrome for biological staining. The free base, Auramine O Base (CAS 492-80-8, Solvent Yellow 34), has been removed from the market in the U.S. because it is a carcinogen. Auramine O has a mean excitation wavelength of 460 nm (blue) and a mean emission wavelength of 550 nm (Wolbers et al., 1990).
