FAQ
Frequently Asked Questions
It is a synthetic red dye, systematically named for its four bromine atoms attached to a fluorescein core. It is standardly called eosin Y and is a vital stain in histology.
Yes, 'eosin Y' specifically refers to tetrabromofluorescein. There is also 'eosin B', which is a different, bluish-red dye.
Only in highly technical contexts such as histology laboratory manuals, chemistry specifications, or scientific papers on dye tracers in hydrology.
It is a systematic IUPAC-style chemical name that precisely describes its molecular structure: the 'tetrabromo' derivative of 'fluorescein'.
A synthetic, brominated derivative of fluorescein, commonly used as a red dye and biological stain.
