C.I. Fluorescent Brightener 28

Description:

C.I. Fluorescent Brightener 28, also known by its CAS number 4193-55-9, is a synthetic organic compound primarily used as a fluorescent whitening agent in various applications, including textiles, paper, and detergents. This compound belongs to the class of stilbene derivatives and is characterized by its ability to absorb ultraviolet light and re-emit it as visible blue light, effectively enhancing the brightness and whiteness of materials. It is typically a white to pale yellow powder, soluble in water and organic solvents, which makes it versatile for incorporation into different formulations. The brightener is stable under normal conditions but may degrade under extreme pH or high-temperature conditions. Its use is widespread in the textile industry to improve the appearance of fabrics, while in the paper industry, it enhances the brightness of paper products. Safety data indicates that it should be handled with care, as it may cause irritation upon contact with skin or eyes. Overall, C.I. Fluorescent Brightener 28 is valued for its optical properties and effectiveness in improving the aesthetic qualities of various materials.

Fluorescent Brightener 28 is a fluorescent dye that is used in the textile industry for staining and as a biological marker. It binds to the cell nuclei, which can be seen under ultraviolet light. Fluorescent Brightener 28 has been shown to have synergistic effects when combined with other dyes such as 4'6-diamidino-2-phenylindole (DAPI) and Thiazole orange. This dye is also used in diagnosis of opportunistic fungal infections, such as C. glabrata, by using flow cytometry or microscopy techniques. Fluorescent Brightener 28 has also been shown to inhibit the growth of wild-type strains of yeast, but not mutants resistant to this compound.
