Basic Red 1 CAS: 989-38-8

98-88-4 cas 989-38-8 basic dyes or Rhodamine 6G or Basic Red 1

Basic Red 1 ( Rhodamine 6G12) is a synthetic dye that can produce a variety of colors on different materials. It is a dark green purple red sparkling crystal that has different solubility and color reactions with different solvents and reagents. When dissolved in water, it shows a crimson color with green fluorescence. When dissolved in ethanol, it changes to red with yellow fluorescence. When treated with concentrated sulfuric acid, it turns yellow and then red when diluted. When mixed with sodium hydroxide, it forms a crimson precipitate. Basic Red 1 is mainly used for dyeing wool, silk, polyamide fiber, and leather by various methods. It can also be used as a fluorescent tracer, a laser dye, and a pH indicator.

USAGE

Rhodamine 6G (Basic Red 1) is a dye that belongs to the class of basic dyes, which are water-soluble and have strong fluorescence. It is mainly used for direct printing of silk and toxic silk fabrics, especially for creating decorative patterns in neutral and acidic conditions, and also be used for dyeing wool, cotton, nylon, and leather, but the color fastness is poor. Moreover, Basic Red 1 can react with phosphotungstic silver acid to form a color lake, which is a type of pigment that can be used for making high-quality inks. Basic Red 1 has the chemical formula C27H29ClN2O3 and the CAS number 3068-39-1.

Basic Red 1 is suitable for direct printing of silk and toxic silk fabrics. It is generally used as a decorative color in neutral and acidic direct dye multi-color printing. It does not print large or medium block alkaline red 6GDN and is suitable for direct printing of silk and toxic silk fabrics. Flower pattern. When used for dyeing wool and cotton fibers, the color fastness is poor. It can be used for coloring leather and paper, as well as for preparing organic pigments. It reacts with phosphotungstic silver acid to form a color lake, which is used as a pigment for producing advanced inks, and can also be used for dyeing nylon, wool, and silk

FAQ

Q: What is the difference between rhodamine B and rhodamine 6G?

A：Rhodamine 6G is a highly fluorescent rhodamine dye primarily used as a tracer dye in water to determine the rate and direction of flow and transport. The chemical formula of Rhodamine 6G is C28H31N2O3Cl, soluble in water and methanol, with an excitation/emission peak of 525/548 nm. Rhodamine 6G can also be used as a laser dye or as a gain medium for dye lasers.

Rhodamine 6GDN is a derivative of Rhodamine 6G, which contains a nitro (NO2) group, giving it higher thermal stability and lower fluorescence quantum yield. The chemical formula of Rhodamine 6GDN is C28H30N3O6Cl, soluble in water and methanol, with an excitation/emission peak of 540/565 nm. Rhodamine 6GDN is mainly used in biotechnology applications such as fluorescence microscopy, flow cytometry, fluorescence related spectroscopy, and ELISA.
