1,4-Diazabicyclo[2.2.2]octane (DABCO; TEDA; Triethylenediamine) (CAS: 280-57-9), is a highly symmetrical molecule with a cage structure. The colorless extremely hygroscopic crystals is a highly nucleophilic tertiary amine base, which is used as a catalyst and reagent in polymerization and organic synthesis.
DABCO is used as polyurethane catalyst, Balis-Hillman reaction catalyst complexing ligand and lewis base. It finds use in dye lasers and in mounting samples for fluorescence microscopy and as anti-fade reagent shown to scavenge free radicals due to flurochrome excitation of fluorochromes.
DABCO is typically used as a catalyst in polymerization reactions. It has a role as a catalyst, a reagent and an antioxidant. It is a bridged compound, a tertiary amino compound, a saturated organic heterobicyclic parent and a diamine.
DABCO is a very important and efficient catalyst in chemical production and is widely used in condensation reaction, polyurethane foaming catalysis, pesticide synthesis and electroplating industries.
Can be used in the production of various products such as polyurethane foam, elastomer and coating.
