Based on its molecular formula C20H7Br2HgO5NaH2O, 129-16-8 M0T18YH28D Merbromin Mercurochrome Merbromin [INN:NF] Disodium salt of 2,7-dibromo-4-hydroxymercurifluoresceine Fluorescein, 2',7'-dibromo-4'-(hydroxymercurio)-, disodium salt Mercury, (2',7'-dibromo-3',6'-dihydroxy-3-oxospiro(isobenzofuran-1(3H),9'-(9H)xanthen)-4'-yl)hydroxy-, disodium salt Asceptichrome Aseptichrome Chromargyre 2,7-Dibromo-4-hydroxymercurifluoresceine disodium salt Disodium 2,7-dibrom-4-hydroxy-mercuri-fluorescein Disodium 2',7'-dibromo-4'-(hydroxymercury)fluorescein DOMF EINECS 204-933-6 Flavurol Fluorochrome Gallochrome Gynochrome Merbromina [INN-Spanish] Merbromine [INN-French] Merbrominum [INN-Latin] Mercuranine Mercurochrome-220 soluble Mercurochromum Mercurocol Mercurome Mercurophage Planochrome HSDB 6800 Merbromina Merbromine Merbrominum UNII-M0T18YH28D contains a salt form, a flavonoid core, a hydroxyl group, an ether linkage, bromine substitution; these features give the compound characteristic absorption bands in UV spectroscopy. The molecular weight of 728.67 g/mol is directly relevant to the identification of the molecular ion in mass spectrometry. The presence of an aromatic ring or conjugated system gives the compound characteristic absorption bands in the UV-Vis region, making it well suited to UV or diode-array detection (DAD).

Recommended for analytical method development and validation; each product is supplied with a full Certificate of Analysis (COA) ensuring ISO 17034 metrological traceability.

The assigned purity is verified by mass-balance and quantitative NMR (qNMR) approaches, with the expanded uncertainty reported at a 95% confidence level (k=2). Batch homogeneity and stability are independently assessed for every lot.
