3 - (2-helix adamantane) - 4-methoxy-4 - (3-phosphoxyyl) - phenyl-1,2-dioxane, abbreviated as amppd, is a chemiluminescent reagent. Amppd and luminol, as we are familiar with, are oxidation reduction luminescent reagents. However, amppd is an ultra-high sensitivity detection reagent for phosphatase, which is different from luminol, which is mainly used in blood detection.
