8-acetoxypyrene-1,3,6-trisulfonic Acid Trisodium Salt by Molecular Depot is a 8-acetoxypyrene-1,3,6-trisulfonic acid trisodium salt, the acetylated precursor of the pH probe pyranine. Acetylating the hydroxyl of pyranine removes the pH sensitivity and the fluorescence, and both return when an esterase or a base cleaves the acetyl group off, which makes the compound a masked probe. It is used as a masked fluorescent pH probe, as an esterase substrate and in membrane transport and fluorescence research. Each unit contains 100 mg. MBP supplies Molecular Depot research reagents to research labs in the United States, Canada and worldwide.
