DOCUMENT TYPE: Journal CA Section: 40 (Dyes, Fluorescent Whitening Agents, and Photosensitizers) Section cross-reference(s): 9, 15, 25 Fluorescein isothiocyanate (I) [27072-45-3] for use in the fluorescent antibody technique was prepd. by the method of Stansilav Smolik (1966) with some modifications to improve the purity and yield. Aminofluorescein [27599-63-9] (7 g), was dissolved in 30 mL MeOH and 30 mL aq. NH3, satd. with NH3 gas at 5°, mixed with 20 mL CS2 during 3-4 h at <10°, stirred for 6 h at 25°, cooled to 5°, dild. with 600 mL ice water, mixed with 200 mL water contg. 50 g FeCl3×6H2O, stirred for 1 h, acidified to pH 1.5-2 with 15% HCl at <10°, and filtered to prep. 7 g crude I.
