FHZ is a highly selective, cell-permeable, non-cytotoxic, non-fluorescent 6-triethylene glycol-substituted fluorescein hydrazide that is an efficient fluorescent turn-on probe for dual channel detection of (oOH) and HOCl in live cells and zebrafish embryos. FHZ selectively reacts with hydroxyl (oOH) and HOCl, respectively, to form highly fluorescent FOBA (Ex: 410 nm & Em.: 486 nm; Φ = 0.42; ε410 = 12000/M/cm) and F-TEG (Ex: 490 nm & Em.: 520 nm; Φ = 0.34; ε490 = 7000/M/cm), while exhibiting no reactivity toward H2O21O2, O2o–, NO, or ONOO–. Cyan and green fluorescence dual-channel detection with two exciting wavelengths (405 nm and 488 nm) and two collection windows (430–490 nm; 510–560 nm) allows time-dependent quantitative detection of cellular oOH and HOCl by FHZ in live cells (50-100 μM; HeLa and RAW 264.7 macrophages) cells and zebrafish embryos (50 μM).

例如，依据体表面积折算法，将化合物用于小鼠的剂量20 mg/kg 换算成大鼠的剂量，需要将20 mg/kg 乘以小鼠的Km系数（3），再除以大鼠的Km系数（6），得到化合物用于大鼠的等效剂量为10 mg/kg。
