Name: SQ-COOH, (Z)-4-((1-(3-carboxypropyl)-3,3-dimethyl-3H-indol-1-ium-2-yl)methylene)-2-(((Z)-1-ethyl-3,3-dimethylindolin-2-ylidene)methyl)-3-oxocyclobut-1-en-1-olate
SQ-COOH is a carboxylic acid far-red squaraine type fluorogenic building block that is useful in the design of probe in biosensing and bioimaging project.
- Polarity-sensitive fluorogenic building block (Turn-on fluorophore)
- Absorption & emission in the far-red (630-700 nm) that enables in vitro & in vivo application
- High brightness owing to its high molar extinction coefficient Ɛ~330000 M-1cm-1
- High chemical stability & photostability
