Description
Colorless needles and plates that forma a red solution. Rosaniline is formed from one molecule of Aniline and two of toluidine. All varieties of magenta dyes are salts this tripheylmethane compound. Chlorination of rosaniline produces Magenta (rosaniline chloride). Currently, rosaniline is used as a Fungicide, fabric Dye, and Ink colorant. It is also a Fluorochrome. It has a mean excitation wavelength of 570 nm (green) and a mean emission wavelength of 625 nm (Wolbers et al. 1990).
