Definition
ChEBI: 1,1'-diethyl-2,2'-cyanine iodide is a 1,1'-diethyl-2,2'-cyanine halide and an organic iodide salt.
General Description
1,1′-Diethyl-2,2′-cyanine iodide is a quinocyanine dye. This photographic sensitizing dye is mainly used in silver halide photography. 1,1′-Diethyl-2,2′-cyanine iodide dye aggregation in dilute aqueous solution displays red and blue shifted absorption bands.
Purification Methods
It crystallises from EtOH and is dried in a vacuum oven at 80o for 4hours. [Beilstein 23 II 267.]
