Dye Stabilizers

Polysciences’ Dye Stabilizers collection includes high-purity chemical additives designed to support the long-term stability of dye solutions and maintain fluorescence performance by quenching reactive oxygen species and other degradative processes. A key example is crystalline 1,4-diazabicyclo[2.2.2]octane (DABCO), which functions as an antioxidant and singlet-oxygen quencher suitable for dye solutions that have not been de‐oxygen-degassed.
