Fluorol Yellow 088 (CAS 81-37-8)

Fluorol Yellow 088, registered under CAS number 81-37-8, is a synthetic fluorescent dye from the xanthene group, known for its intense yellow fluorescence. This dye is particularly noted for its high quantum yield, which makes it an excellent choice for a variety of applications in scientific research that involve fluorescence microscopy and spectroscopy. The primary mechanism of action of Fluorol Yellow 088 involves the absorption of light at specific wavelengths, followed by the emission of light at a longer wavelength. This shift from higher energy absorption to lower energy emission is characteristic of fluorescent substances and is utilized in research to visualize and track biological materials. In non-medical research contexts, Fluorol Yellow 088 is extensively used to stain and study the dynamics of lipids and lipid-containing structures within cells, due to its lipophilic nature. This property allows it to integrate into cellular membranes, making it useful for examining cell membrane fluidity and organization. Additionally, it has been applied in the field of polymer science to investigate the distribution and stability of polymeric materials under various conditions, as its fluorescence can reveal interactions and the behavior of polymers at the molecular level. The use of Fluorol Yellow 088 in these research areas provides crucial insights into cellular and material structures, enhancing the understanding of complex biological and synthetic systems.
