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.

Tetrabromofluorescein is usually exclusively scientific/technical in register.

Tetrabromofluorescein: in British English it is pronounced /ˌtɛtrəˌbrəʊməʊˌflʊəˈrɛsiːɪn/, and in American English it is pronounced /ˌtɛtrəˌbroʊmoʊˌflʊˈrɛsin/. Tap the audio buttons above to hear it.

Memory Aids

Mnemonic

Think: 'TETRA' (four) 'BROMO' (bromine atoms) added to 'FLUORESCEIN' (a fluorescent dye). Four bromines make the red dye shine.
