Rhodamine 6G Chemical Properties,Usage,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 dyes are used extensively in biotechnology applications such as?fluorescence microscopy,?flow cytometry,fluorescence correlation spectroscopy?and?ELISA.

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.

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

Rhodamine 6G is a rhodamine 6G(1+), an organic chloride salt and a xanthene dye. It has a role as a fluorochrome.

General Description

Bright bluish-pink crystals or reddish purple powder.

Air & Water Reactions

Insoluble in water.

Health Hazard

ACUTE/CHRONIC HAZARDS: When heated to decomposition Basic Red 1 emits very toxic fumes.

Fire Hazard

Flash point data for Basic Red 1 are not available. Basic Red 1 is probably combustible.

Flammability and Explosibility

Not classified

Biological Activity

Rhodamine 6G is a rhodamine analog useful in P-glycoprotein (Pgp) efflux assays. It has been used to characterize kinetics of multidrug resistance protein 1 (MRP1)-mediated efflux.
A rhodamine analog useful in Pgp efflux assays. Has been used to characterize kinetics of MRP1- mediated efflux.

Biochem/physiol Actions

Rhodamine 6G is a rhodamine analog useful in P-glycoprotein (Pgp) efflux assays. It has been used to characterize kinetics of multidrug resistance protein 1 (MRP1)-mediated efflux.

Safety Profile

Poison by ingestion and intraperitoneal routes. An experimental teratogen. Mutation data reported. Questionable carcinogen with experimental tumorigenic data. When heated to decomposition it emits very toxic fumes of Cland NOx.

Properties and Applications

bright blue light pink. Purple powder or flash of green light crystallization. Soluble in water for big red, with strong green fluorescent, soluble in ethanol for red, with the yellow fluorescence. In the thick of the acid is yellow, diluted in red. Dye with sodium hydroxide solution with a red precipitate. Mainly used in the manufacture of color break, used in ink. Can also be used for cotton, wool and silk dyeing.
