C.I. Solvent Green 3 is a green dye, an is a green dye, an anthraquinone derivative..

C.I. Solvent Orange 2 is an agent of dye.

Solvent Yellow 93, an azomethine dye, is used as a colorant of toner.

Sudan II (Solvent Orange 7) is a dyes.

Pyranine (Solvent Green 7) is reported as a new class of fluorescent chemosensor for the Cu+ ion.

Auramine is an agent of dye.

Sudan III (Solvent Red 23) is a solvent dye used to color nonpolar substances.

D&C Red No. 27 Aluminum Lake is a drug and cosmetic synthetic dye. The FDA lists it as a safe additive for drugs and cosmetics as per FDA standards.

Fluorescein (Solvent Yellow 94) is a phthalic indicator dye, use as a synthetic fluorescent tracer.

4',5'-Dibromofluorescein (Eosinic acid) is a fluorescent dye that can be used as a ligand for protein characterization by spectroscopic analysis.

4-Methylumbelliferyl palmitate serves as a potent fluorophore to assay acid lipase activity in human leukocytes, with its fluorescence significantly affected by acidity and solvent properties. In near-neutral aqueous solutions, it predominates in a neutral molecular form, emitting strong fluorescence at 445 nm, whereas in weakly alkaline solutions, it primarily exists in an anionic form, resulting in even stronger fluorescence at the same wavelength [1] [2].

9-(2,2-Dicyanovinyl)julolidine (DCVJ) is a fluorogenic dye that is considered a fluorescent molecular rotor because its properties depend on the rotational relaxation of the molecule, which can be influenced by the viscosity of the solvent used. It has an excitation maximum at approximately 450 nm, and its emission is approximately 480 or 505 nm for low or high viscosity solvents, respectively. DCVJ has been used to study tubulin dynamics because its fluorescence increases when bound to tubulin sheets but is lower when bound to microtubules.

Prodan, a solvatochromic fluorophore, serves as a sensitive reporter for microenvironment changes in membranes. Utilizing Prodan's chemistry, researchers have designed and synthesized fluorescent nucleosides that exhibit a sensitive variation in their Stokes shift values, reflecting the orientational polarizability of the solvent.
