Product Name:Fluorescein dibutyrate
English Name:Fluorescein dibutyrate
CAS No.:7298-65-9
Aliases:Fluorescein di-n-butyrate, Di-n-butyryl fluorescein, FDB
Molecular Formula:C28H24O7
Physical Properties:Yellow to orange crystalline powder. Insoluble in water; soluble in organic solvents such as DMSO, methanol, and ethanol. Melting point: approximately 135-140°C. Store at -20°C, protected from light. Upon hydrolysis, releases fluorescein with fluorescence characteristics (excitation ~490 nm, emission ~514 nm).
Uses:Used as a fluorogenic substrate for detecting esterase and lipase activity. It is hydrolyzed by esterases or lipases to release fluorescein, enabling quantitative analysis through fluorescence signals. Widely applied in biochemistry, cell biology, and clinical diagnostics.
