TMB (monosulfate)

TMB monosulfate is the monosulfate form of TMB (HY-15930) . TMB monosulfate is a non-toxic, non-mutagenic, colorless dye that is also used as a chromogenic agent in enzyme detection systems based on horseradish peroxidase (HRP) . TMB monosulfate can function as a photoacoustic probe for reactive oxygen and nitrogen species (ROS/RNS), reacting with hypochlorite, hydrogen peroxide, singlet oxygen, and nitrogen dioxide to produce blue oxidation products. TMB monosulfate can detect the singlet oxygen produced by the outer membrane of Escherichia coli ATCC 25922[1][2].
