Fluorescein, tetrachloro

Tian and co-workers [148] have reported the synthesis of two chlorinated fluoresceins probes 4,7,2,7 -tetrachloro-6-(5-carboxypentyl) fluorescein and 4,7,4,5 -tetrachloro-6-(5-carboxypentyl) fluorescein for labeling proteins. More recently, the same research group has described the synthesis of two novel chlorinated fluoresceins, namely 2,4, 5, 7 -tetrachloro-6-(5-carboxypentyl)-4,7-dichloro fluorescein succinimidyl ester 52 and 2, 4, 5, 7-tetrachloro-6-(3-carboxypropyl)-4,7-dichlorofluorescein succinimidyl ester 53 [149].
