Ethanedioic acid, 1-methyl 2-(4-methyl-2-oxo-2H-1-benzopyran-7-yl) ester

Description

Chemodosimeter 1 was designed to function as a highly selective phosphate ion (Pi) sensor, showing a 91-fold ratiometric fluorescence enhancement. The probe successfully visualized exogenous and endogenous apyrase-catalyzed Pi generation and was the first probe able to trace the generation and enrichment of Pi through hemichannel closure in Sf9 cells.
