    Product Description

    Angeli’s salt is regarded as a classical nitroxyl (NO-) donor, but under certain conditions evolution of NO is also observed.1 It spontaneously dissociates in a pH-dependent, first-order process with a half-life of 2.3 minutes at 37°C (pH 7.4) to liberate 0.54 moles of NO per mole of parent compound.1,2

    WARNING This product is not for human or veterinary use.
