NIR dye-1 (Compound 1h) is a near-infrared (NIR)fluorescent dye. NIR dye-1 has absorption and emission in the NIR region, while retaining an optically tunable hydroxyl group^[1].

To demonstrate the feasibility of developing water-soluble NIR dyes, NIR dye-1 (Compound 1h) is further synthesized, which bears several water-soluble groups. As expected, dye NIR dye-1 (Compound 1h) is soluble in pure PBS and newborn calf serum (without addition of any co-organic solvent) with a solubility of at least 2 mM in PBS and 3 mM in newborn calf serum^[1].
