Fluorescent brightener 28 (Technical Grade)

Catalog No.: B11090
Photoinitiator/Fluorescent Whitening Agent
Fluorescent Brightener 28 is a fluorescent whitening agent and photoinitiator that enhances brightness in textile applications. It effectively stains polysaccharides like cellulose, weakly labeling the cytoplasm and intensely marking the cell nucleus upon plasma membrane disruption. This compound is also employed for detecting intracellular chitin within living cells and serves as a light-sensitive photoinitiator for free radical photopolymerizations using visible LED light. Its versatile applications make it a valuable tool in both biological research and material science.
