TMB dihydrochloride x.hydrate

TMB (dihydrochloride x.hydrate) is the dihydrochloride salt and hydrate form of TMB. It is a non-toxic and non-mutagenic colorless dye used as a chromogenic agent in horseradish peroxidase-based assay systems. This compound also serves as a photoacoustic probe for reactive oxygen and nitrogen species (ROS/RNS), reacting with hypochlorite, hydrogen peroxide, singlet oxygen, and nitrogen dioxide to produce a blue oxidized product. Additionally, TMB (dihydrochloride x.hydrate) can detect singlet oxygen produced by the outer membrane of Escherichia coli ATCC 25922.
