A reactive disperse yellow dye is suitable for supercritical CO.sub.2 anhydrous dyeing. The reactive disperse yellow dye in has a parent of azo structure, and has monochlorometriazinyl groups thereon. The reactive disperse yellow dye can be used for supercritical CO.sub.2 anhydrous dyeing of cellulose fiber, protein fiber, chemical fiber and the blended fabrics thereof, and has good dyeing effect particularly for cotton-polyester blended products.

A compound of Formula (I) or a pharmaceutically acceptable ester, amide, solvate, or salt thereof, or a salt of such an ester or amide or a solvate of such an ester amide or salt, is disclosed. Compositions comprising the compound and methods of use are also disclosed. Those dimeric Evans Blue derivatives, denoted as N(tEB)2, reversibly bind two molecules of albumin via the two albumin binding regions of each NtEB in the dimer, resulting in significantly increased binding affinity to albumin and extended circulation half-life in vivo. Further, when the N(tEB)2 is conjugated to a peptide therapeutic, the in situ formation of the complex of N(tEB)2 with two albumin molecules resulted in increased resistance of the peptide therapeutic from proteolysis.
