Description:
Lipophilic fluorescent pH indicator used to assay biogenic amines with optodes. The deprotonated version enables excitation with red light (LED) (Ex/Em: 605/680nm) versus the acidic form (Ex/Em: 520/600nm). The ester functionality renders the indicator molecule lipophilic and water-insoluble but also prevents lactonization of the dye in an apolar environment.
