Chemical Name: Sodium 4-(2-((1E,3E,5E,7Z)-7-(1,1-Dimethyl-3-(4-sulfonatobutyl)-1,3-dihydro-2H-benzo[e]indol-2-ylidene)hepta-1,3,5-trien-1-yl-1,2,3,4,5,6,7-d7)-1,1-dimethyl-1H-benzo[e]indol-3-ium-3-yl)butane-1-sulfonate
Biological ActivityICG-d7 is a partially deuterated form of near-infrared fluorescent dye Indocyanine Green (ICG; Cat. No. 7510). Operates in the 700 - 900 nm wavelength range; also exhibits fluorescence emission in the shortwave infrared window (SWIR; 1,000 - 2,000 nm) which enables in vivo imaging. ICG-d7 shows improved stability in aqueous solutions over ICG with the same fluorescence brightness, and similar absorption and emission maxima in both DMSO and FBS. Excitation maximum = 794 nm; emission maximum = 818 nm.
