Rhodamine 6G Chemical Properties, Uses, Production
Description
Rhodamine 6G is one the most effective laser dyes in recovering latent prints on various non-porous surfaces. This dye is normally used on non-porous surfaces, but may, under certain conditions, be used on porous or semi-porous surfaces. Rhodamine 6G is extremely efficient as it is highly fluorescent and can be used with various alternate light sources.
Rhodamine 6G has been used as a leukocyte marker to study the interaction between leukocytes and the vascular endothelium. It has also been used to label platelets.
Chemical Properties
dark reddish purple, brown or black crystalline solid
Uses
Rhodamine 6G (R6G) is an organic laser dye and can be used to study the probes as it has a high quantum yield for fluorescence. It can be used as a fluorescence tracker which helps in defining the spectroscopic characteristics for achieving a high conversion efficiency and precision of measurements. The absorption of R6G in different solvents can range between 400-700 nm.
Uses
Rhodamine 6G has been used as a leukocyte marker to study the interaction between leukocytes and the vascular endothelium. It has also been used to label platelets.
Uses
Rhodamine dyes are used extensively in biotechnology applications such asfluorescence microscopy,flow cytometry,fluorescence correlation spectroscopyandELISA.
Application
R6G can be used as a cationic dye to determine the photocatalytic ability of TiO2 reinforced graphene oxide composites that can be potentially used in self-cleaning applications. It can be used to calculate the quantum yield of glutathione-capped copper nanoclusters (CuNCs) for fluorescent thermo-responsive nanomaterials and gold nanoparticles (AuNPs) for fluorescent/X-ray computed tomography.
Preparation
3-(Ethylamino)-4-methylphenol and Phthalic anhydride to afford the product was obtained ethanol and an inorganic acid esterification; O-Methylaniline with ethylene oxide Alkylation , sulfonated, alkali fusion, and Phthalic anhydride condensation, and then use ethylene oxide esterification.
Definition
