CAS 56897-54-2 — Kaliumtetrabromfluorescein

Tetrabromofluorescein potassium salt is a synthetic fluorescent dye, primarily used as a pH indicator in laboratories and analytical chemistry, particularly for detecting alkaline conditions (pH 3.8–5.4). It appears yellow in acidic solutions and turns pink or red in basic environments, making it useful for titrations and qualitative analysis. This chemical has a CAS number of 56897-54-2, with the molecular formula C20H6Br4K2O5 and a molecular weight of 724.08 g/mol. Store it at 2–8°C, and handle it with caution—it carries a **Warning** signal word for potential hazards. Molekula supplies Tetrabromofluorescein potassium salt from research to bulk quantities with full documentation and ISO 9001:2015 traceability.
